Byzantine Church is the Eastern Church that prays to the divinity of Christ.

They follow the Greek language in their religion, and even though Bishops hold the highest power, they are never thought to be infallible and more powerful than the church.

Roman Catholics are inclined to believe in the humanity of Jesus, and they give utmost power to their Pope.

The religion holds many Biblical notions as to their beliefs and considers Mary to be virgin and free from the ‘original sin’.

They worship statues, and during liturgies, the use of several instruments are seen.

What is Byzantine?

The Byzantine Church was formally known as Eastern Church that was spread in Northern Africa and the Middle East. The belief of this Church is focused on the divinity of Jesus rather than his humanity.

Greek is the official language of this Church, and they do not follow any Latin rules.

The followers of the Church pray to the icon.

Byzantines used leavened bread during the Divine Liturgy. This symbolizes the risen Christ.

The head of the church is the Highest Bishop, but he is never considered to be higher than the church itself, and he is not regarded as infallible.

Religious thinking can be marked as very poetic, and the prayers tend to get repeated.

Eastern theology does not include the concept of Purgatory and Stations of Cross, but they have the notion of Original Sin, and according to them, Mary has committed the original sin.

Eastern Orthodoxy has the rule of priests getting married before they are appointed to the post.

What is Roman Catholic?

Roman Catholicism influenced the areas of Western Europe, as well as the Northern and Western parts of the Mediterranean. The Pope is the highest of this Church and is assumed to be infallible.

This church has no place for the Greek language in the scriptures. They only regard the Latin language to be authorized. 

Roman Catholics use unleavened bread because that is what Jesus used in the Last Supper. Roman Catholics put priority on the human side of Christ.

Catholics have statues to pay their homage to.

The church believes in the Purgatory stage, and Stations of Cross is also accepted by this religion. 

Catholics believe in ‘original sin’, but they do not think that Mary engaged in any sin. The Catholics have a strict policy regarding the marriage of their priests; the priests are not allowed to marry under any circumstances.

This religion is linear, and their prayers are very simple and do not have repetitive verses.
