Difference Between Catholic and Orthodox

Churches are divided into two different types; the Catholic church and the orthodox church. Their faith is based on the god-spell of Jesus- the Holy Bible.

They believe in the Trinity. Their motto is to convert people from other religions; the Christian denomination.

Catholic vs Orthodox 1

The Catholic church is one of the oldest institutes; still functioning. It gives the Pope (Bishop of Rome) the supreme authority – Vicar of Christ.

Here the doctrines are more prone to changes over the years. The Pope of the Catholic church is endowed with Petrine ministries.

On the contrary, the Orthodox church’s Pope is not considered as infallible. Hence is not given the supreme authority. Here children are involved early in the congregation. This church has no central governmental or doctrinal authority.

What is Orthodox?

The orthodox church is also known as the Eastern Orthodox church. It is the second-largest Christian church. It is also one of the oldest religious institutes in the world.

It has influenced the culture of eastern and south-eastern Europe and history too. These churches are governed by Bishops in local synod and are operated as the communion of the autocephalous. 

The Pope is not considered infallible by the orthodox church. Orthodox priests are allowed to marry, contrary to the Catholic priests. The honor of primacy is given to the patriarch of Constantinople. Yet being considered and given highest status amongst all; he does not have authority over churches.

The Eastern Orthodox Church considers Jesus Christ as the head while the Church is considered to be a body.

It is believed by the Orthodox Christians that the grace of God and authority are foreowned by the Bishops and clergy. It is handed down by laying on hand; a practice initiated by the apostles.

They differentiate between God’s eternal essence and his indigenous energies as a relationship of God and his creations.

This is the way in which he (the God) reaches humanity. The Julian calendar is followed by the autocephalous churches and the rest follow the revised Julian calendar.

They do not believe in purgatory. There is no compulsion for confession of their sins.
