Question 1 of 12.

The Orthodox view of salvation

According to the Orthodox beliefs, how can a Christian obtain salvation?

Salvation is "faith working through love" and should be seen as a life long process. The Ultimate aim is to obtain Theosis or union with God. This is done through living a holy life and seeking to draw closer to God.
Salvation is the free and unmerited gift of God to man. It is obtained by grace through faith in Christ alone.
Salvation is by grace, specifically sanctifying grace, which is given initially through Baptismal regeneration and then maintained through the Sacraments.

A life-long process

Salvation is "faith working through love" and should be seen as a life long process. The Ultimate aim of every Orthodox Christian is to obtain Theosis or union with God. This is done through living a holy life and seeking to draw closer to God.

Question 2 of 12.


Purgatory painting

Which of the three major Christian groups (denominations) adheres to the doctrine of the Purgatory?



In the Catholic faith, Purgatory is an intermediate state of cleansing and preparation for heaven. Also a state where the punishment due to unremitted venial sins may be expiated.

Question 3 of 12.


painting of The Christian Trinity

Which two of the Christian Churches (denominations) agree upon the doctrine of the "filioque" (the doctrine according to which The Holy Spirit proceeds from both The Father and The Son)?

The Orthodox and the Catholic
The Orthodox and the Protestant
The Catholic and the Protestant

The Protestants and the Catholics

The Catholic Church agrees with the Protestant view in regards to The Holy Spirit proceeding from both the Father and the Son. The Nicene creed includes the filioque (Latin: 'and the son'). Ambrose of Milan (340-397) wrote: "When the Holy Spirit proceeds from the Father and the Son, He is not separated from the Father, He is not separated from the Son".

Question 4 of 12.

Accepted by Protestantism

Which of the following is accepted by (several subgroups of) Protestant Christianity?

Veneration of the saints
Female ordination
Papal authority and infallibility

Female ordination

Many Protestant churches practice female ordination, including those within the Anglican communion, where the issue of female episcopacy is currently being discussed.

Question 5 of 12.


What is "Transubstantiation", according to the Catholic faith?

the belief that the bread and wine do not change substance during the Eucharist
the belief that the bread and wine change completely into Christ's body and blood during the Eucharist
the belief that certain substances can be used to preserve the bodies of saints uncorrupted

The gifts change into the actual body and blood of Christ

In the Catholic Church, as in Orthodoxy, the Priest invokes the Holy Spirit during the Mass. The consecration becomes effective through the Priest, who acts in the person of Christ. The gifts change completely into Christ's body and blood and this change is termed 'Transubstantiation' (i.e. the outward appearance remains the same, but the substance changes).

Question 6 of 12.

The Virgin Mary in Orthodoxy

What are the Orthodox beliefs about the Assumption and the Immaculate conception of Mary?

Both the Assumption and the Immaculate conception of Mary are accepted by Orthodox Church
Both the Assumption and the Immaculate conception of Mary are rejected by the Orthodox Church
The Assumption is accepted and it is agreed that Mary experienced physical death, but the Immaculate conception is rejected.

Assumption - yes, but not Immaculate conception

In the Orthodox faith, the Assumption of Mary is accepted and it is agreed that Mary experienced physical death, but the Immaculate conception is rejected. Orthodox belief is that the guilt of original sin is not transmitted from one generation to the next, thus obviating the need for Mary to be sinless.

Question 7 of 12.

Rejected parts of the Scripture

Which parts of the Scripture, accepted by Orthodoxy and Catholicism, does Protestantism reject?

The Letter of Jude
The Deuterocanonicals
The Book of Deuteronomy

The Deuterocanonicals

The Orthodox and the Catholic Churches accept the 39 Old Testament and 27 New Testament books, but also a collection of books not found in the original Hebrew Bible. These are known as Deuterocanonicals  (i.e. a second canon of scripture). Protestantism rejects the Deuterocanonicals as not being inspired scripture and term them Apocrypha (Greek: 'Hidden Things').

Question 8 of 12.

The Pope in Catholicism

What authority does the Pope have in the Catholic Church?

No authority whatsoever
No greater or lesser authority than any of his fellow Bishops in the church
He is the 'Vicar of Christ', the visible head of the church on Earth and spiritual successor of St. Peter

The Vicar of Christ

In the Catholic Church, the Pope is the 'Vicar of Christ' (i.e. the visible head of the church on earth and spiritual successor of St. Peter). He has supreme authority (including that over church councils) within Christendom (The Power of the keys).

Question 9 of 12.

Catholic distribution of the Eucharist

Are Christians who are not members of the Catholic Church allowed to receive the Eucharist?

Yes, but only the women and the children


As with Orthodoxy, in the Catholic Church only members of the church may receive the Holy Eucharist. In some Catholic Churches, the bread alone is given to the congregation, the Priest receiving the wine. However, it is becoming common for churches to have communion in both kinds.

Question 10 of 12.

Protestant foundational principle

Which of the following is a foundational principle of Protestantism?

Apostolic succession
Sola Scriptura
The veneration of the saints

Sola Scriptura

Sola Scriptura (Scripture alone) is the only infallible guide and the final authority on matters of Christian faith and practice (it is one of the foundational principles of Protestantism).

Question 11 of 12.

Clerical celibacy


Which of the three major Christian groups (denominations) require that all priests and bishops be celibate?



All Catholic clergy are required to be male. Priests and Bishops must also be celibate, with the exception of Eastern Rite Catholics and Anglican married clergy who subsequently convert to Catholicism. These groups are allowed to have married priests.

Question 12 of 12.

How many sacraments?


How many sacraments do the Orthodox and Catholic Churches recognize?


7 Holy Sacraments

In the Catholic Church, the number of Sacraments is fixed at seven and is the same list as that in Orthodoxy, with the exception of Chrismation, which is generally known as 'Confirmation'. Orthodoxy recognizes the 7 Holy Sacraments, but doesn't consider the list to be fixed.

  1. Hey, how’s it going?

    I want to pass along some very important news that everyone needs to hear!

    In December of 2017, Donald Trump made history by recognizing Jerusalem as the capital of Israel. Why is this big news? Because by this the Jewish people of Israel are now able to press forward in bringing about the Third Temple prophesied in the Bible.

    Jewish Rabbis have publicly announced that their Messiah will be revealed in the coming years who will be a leader and spiritual guide to all nations, gathering all religions under the worship of one God.

    Biblical prophecy tells us that this Jewish Messiah who will take the stage will be the antichrist “who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God” (2 Thessalonians 2:4). For a time he will bring about a false peace, but “Therefore when you see the ‘abomination of desolation,’ spoken of by Daniel the prophet, standing in the holy place (Matthew 24:15)…then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be” (Matthew 24:21).

    More importantly, the power that runs the world wants to put a RFID microchip in our body making us total slaves to them. This chip matches perfectly with the Mark of the Beast in the Bible, more specifically in Revelation 13:16-18:

    “He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name.

    Here is wisdom. Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666.”

    Referring to the last days, this could only be speaking of a cashless society, which we have yet to see, but are heading towards. Otherwise, we could still buy or sell without the mark amongst others if physical money was still currency. This Mark couldn’t be spiritual because the word references two different physical locations. If it was spiritual it would just say in the forehead. RFID microchip implant technology will be the future of a one world cashless society containing digital currency. It will be implanted in the right-hand or the forehead, and we cannot buy or sell without it. Revelation 13:11-18 tells us that a false prophet will arise on the world scene doing miracles before men, deceiving them to receive this Mark. Do not be deceived! We must grow strong in Jesus. AT ALL COSTS, DO NOT TAKE IT!

    “Then a third angel followed them, saying with a loud voice, “If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation. He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name” (Revelation 14:9-11).

    People have been saying the end is coming for many years, but we needed two key things. One, the Third Temple, and two, the technology for a cashless society to fulfill the prophecy of the Mark of the Beast.

    If you haven’t already, it is time to seek God with all your heart. Jesus loves you more than you could imagine. He wants to have a relationship with you and redeem you from your sins. Turn to Him and repent while there is still hope! This is forever…God bless!


    We all know God exists. Why? Because without Him, we couldn’t prove anything at all. Do we live our lives as if we cannot know anything? No. So why is God necessary? In order to know anything for certain, you would have to know everything, or have revelation from somebody who does. Who is capable of knowing everything? God. So to know anything, you would have to be God, or know God.

    A worldview without God cannot account for the uniformity and intelligibility of nature. And why is it that we can even reason that God is the best explanation for this if there is no God? We are given reason to know or reject God, but never to know that He does not exist.

    It has been calculated by Roger Penrose that the odds of the initial conditions for the big bang to produce the universe that we see to be a number so big, that we could put a zero on every particle in the universe, and even that would not be enough to use every zero. What are the odds that God created the universe? Odds are no such thing. Who of you would gamble your life on one coin flip?

    Is there evidence that the Bible is the truth? Yes. Did you know that the creation accounts listed in the book of Genesis are not only all correct, but are also in the correct chronological order? That the Bible doesn’t say the Earth was formed in six 24-hour days but rather six long but finite periods of time? That the Bible makes 10 times more creation claims than all major “holy” books combined with no contradictions, while these other books have errors in them? The Bible stood alone by concurring with the big bang saying, “In the beginning God created the heaven and the earth” (Genesis 1:1); and says our universe is expanding, thousands of years before scientists discovered these things. Watch a potential life-changing video on the front page of http://WWW.BIBLEFREEDOM.COM with Astronomer(PhD) Hugh Ross explaining all these facts based on published scientific data. He has authored many books, backed even by atheist scientists.

    Jesus came to pay a debt that we could not; to be our legal justifier to reconcile us back to a Holy God; only if we are willing to receive Him: “For the wages of sin is death…” (Romans 6:23).

    God so loved the world that He gave us His only begotten son, so that whoever believes in Him, through faith, shall not perish, but have everlasting life. Jesus says if we wish to enter into life to keep the commands! The two greatest commands are to love God with all your heart, soul, strength, and mind; and your neighbor as yourself. All the law hang on these commands. We must be born of and lead by the Holy Spirit, to be called children of God, to inherit the kingdom. If we are willing to humble ourselves in prayer to Jesus, to confess and forsake our sins, He is willing to give the Holy Spirit to those who keep asking of Him; giving us a new heart, leading us into all truth!

    Jesus came to free us from the bondage of sin. The everlasting fire was prepared for the devil and his angels due to disobedience to God’s law. If we do the same, what makes us any different than the devil? Jesus says unless we repent, we shall perish. For sin is the transgression of the law. We must walk in the Spirit so we may not fulfill the lusts of the flesh, being hatred, fornication, drunkenness and the like. Whoever practices such things will not inherit the kingdom (Galatians 5:16-26). If we sin, we may come before Jesus to ask for forgiveness (1 John 2:1-2). Evil thoughts are not sins, but rather temptations. It is not until these thoughts conceive and give birth by our own desires that they become sin (James 1:12-15). When we sin, we become in the likeness of the devil’s image, for he who sins is of the devil (1 John 3:8); but if we obey Jesus, in the image of God. For without holiness, we shall not see the Lord (Hebrews 12:14).

    The oldest religion in the world is holiness through faith (James 1:27). What religion did Adam and Eve follow before the fall? Jesus, Who became the last Adam, what religion does He follow? Is He not holy? He never told us to follow the rituals and traditions of man but to take up our cross and follow Him (Luke 9:23). There are many false doctrines being taught leading people astray. This is why we need the Holy Spirit for discernment. Unlike religion, holiness cannot be created. It is given to us from above by the baptism of the Spirit. Jesus is more than a religion; He is about having a personal relationship with the Father. Start by reading the Gospel of Matthew, to hear the words of God, to know His character and commandments. Follow and obey Jesus, for He is the way, the truth, and the life!
