What are the differences between Catholics and Greek Orthodox?
819527
Very similar.  Greek Orthodoxy is a national church.  Catholicism is more universal in its leadership an application of faith.  Calendars for feast days do differ at times.  Prayers, saints, liturgies are similar.

Well, that would require a 100 page essay to list all the differences, and a major history language.\n\nBoth would be preferred , at least by me, over Roman Orthodox, but I would say Coptic would be closer to what the church was like after Jesus' death/Resurrection.

A Christian is one who follows Christ. Catholics are Christians but not all Christians are Catholic. A Christian can be Catholic, Methodist, Baptist, Presbyterian, etc.

Well I am Roman Catholic so I am closer to Orthodox Christianity than to Protestantism.\n\nWhat I see in those conversions is that people begin to sense the paradox inherent in Sola Scriptura and the absence of authority in interpretation of the scriptures. Commonly these conversions arise from research into theology and that of the history of the Christian Church.\n\nThe ones I've read tend to delve into the man-made doctrines and traditions of the Protestant Reformed faiths. They usually mention the traditions of the Church Fathers and the congruent and common traditions that arose in the earliest churchest and still are present today as not being in the Protestant faith.\n\nThe paradox I was describing earlier seems to me to be about the lack of accountability in defining doctrine. Since the Bible is the rule of faith alone there is no rule of faith which can interpret the Bible. Everyone is left to their own interpretation and becomes a church unto himself.\n\nThe attraction to Orthodox may lie in the explanations and lack of paradox contained in the above paragraph.\n\nFurthermore, Orthodox churches tend to believe that they are sinners and need to abide in God's will. Whereas Protestants can easily be lulled away from Reformed tradition and believe that they can't go wrong even while sinning. People become disillusioned with the 'once saved always saved' tradition made a couple hundred years ago. They seek to have faith and to live out that faith with a church that will support them in this and not merely say they are saved once and for all.\n\nThis is what I get from many of the Orthodox conversion stories.\n\nI relate a bit since my faith is similar. I think Roman Catholics that convert to Orthodox typically lie in the realm of being of the same faith as your spouse and sometimes in the belief that Christ did not intend a Pope, but intended all those other things the Catholic Church does.

Christian protestant churches teach Scripture.  The bible is the authority.\nOrthodox churches teach some Scripture, but much like the Catholic church, they teach traditions as well.  \nThe Orthodox make a big thing about Mary and their Icons as well.

Catholics are merley one of the many christian denominations.  actually the first one. And with the Orthodox church the only ones for 1500 years.

The Catholic Church also has the "same pattern" of bishop (episkopos in the Greek original), priest (presbyteros), and deacon (diaconos.) What distinguishes us is apostolic succession: a Catholic or East Orthodox priest can show how the line of ordinations in his history takes him right back to the laying on of hands of one of the apostles.\n\nHowever, I'm not going to argue that this is what makes an apostle. What makes someone an apostle is when every facet of his or her life is a response to that simple challenge issued to the original apostles: "Follow me."

Protestants believe that the bible is the authority.  They teach what Christ and the apostles taught.\nCatholics believe that the pope is the authority.  They teach the traditions that he makes up.  Many of these traditions go against the teaching of christ.  This is the reason that the Protestants separtated from the Catholic church.

Really basic - Catholics believe that St. Peter was appointed by Jesus as the first Pope and leader of the church in perpetuity to spread His word and represent Christ on earth, protestants don't belive that. There are many, many differences in praticing the faith. Catholic - priests may not marry, during the Mass a Priest blesses the "host" (wafer, bread,etc) and it becomes the body of Christ to be consumed by people at communion, Catholics confess their sins and, if they are truly repentant a Priest may absolve them from their sins just as Jesus would; Catholics believe we are all born with the original sin from Adam and Eve and that babies must be baptized in order to become pure and a child of God...so many little things. Both faiths believe that there is one God - and so do Sikhs, by the way.

Like the answerer above me, I too went through the RCIA and none of my immediate family is Catholic. In fact, my mother is still very much against religion and against Christianity in particular.\n\nIf you are baptized, confirmed, and believe in the authority given by Jesus to the Church, and to the office of the Pope in particular, and therefore fully accept all dogma and doctrine that the Magisterium of the Church teaches then you are a true Catholic.\n\nCatholic means universal. So Catholic Church means universal Church. To be Catholic means being of one mind and one faith in communion with the Church which is the body of Christ. \n\nIf one insists on following their own individual beliefs apart from the dogma or doctrine of the Church then they are not Catholic because they are isolating themselves from the universal family of the Church. They are not universal, so they are not Catholic.

Catholicism and Biblical Christianity are divergent religions. They are built on different foundations, and they propose different ways of salvation.\n\nIn principle, Christianity is built solely on the Holy Scriptures, the written Word of God. The Bible is our only infallible rule of faith, being sufficient to give us the sure knowledge of the Gospel for our salvation and holiness.\n\nRoman Catholicism demands submission of the intellect and will to the doctrines taught by the Roman magisterium (the Pope and bishops). It is claimed that the Catholic Church derives its doctrines from the "sacred deposit" found in Scriptures and Sacred Tradition. However the faithful cannot verify these doctrines by referring to the original sources. The Scriptures are inaccessible because only the magisterium is able to establish the authentic meaning. Similarly the contents of Sacred Tradition can only be known through the magisterium. Roman Catholicism is mental and spiritual slavery to the Vatican.\n\nAs expected, since the foundations are different, so also are the edifices built upon them. Christianity stands on the Gospel of God's sovereign grace. In love, God predestines His chosen ones to be adopted as sons through Jesus Christ, their sole mediator. The Son became man and gave His life as a ransom to secure their freedom from sin. Being dead in sin, they are completely unable to convert ourselves or merit God's favour. Therefore God graciously grants His people repentance and faith to turn to Him and trust in Christ Jesus for salvation. Believers are accepted in Christ, solely on the merit of His righteousness and blood, and not because of any goodness or human merit. God also resides in His people by the Holy Spirit, enabling them to obey and glorify the Father, and to guarantee their inheritance in heaven forever.\n\nRome's "gospel" is not good news at all. The Roman institution, calling itself "The Church", usurps Christ's mediatorial office, proclaiming herself as the "sacrament of salvation." The "Church" dispenses salvation to her faithful in small portions, starting at baptism and continuing throughout life. Forgiveness can only be obtained through the sacrament of penance. The benefits of Christ's sacrifice are accessible through the sacrifice of the Mass. Instead of teaching the faithful to rest in Christ by faith, Catholics are taught to perform religious works to "merit grace" and to do penance to make satisfaction. Even after death, Catholics remains dependent on the "Church" to relieve their suffering in Purgatory by masses and indulgences.\n\nThe Roman Catholic Church is a mighty obstacle to anyone seeking salvation, enslaving millions of people to a religious system and preventing them from coming directly to Christ.\n\nThe choice is between the Bible and the Roman magisterium; the choice is between salvation by grace through faith in Christ, or through human merit and effort in the Roman religion.

Alleluia! Praise the Lord! Glad you've seen through this, mate! The dilemma you describe is known in theology as the heresy of antinomianism (you might want to do a web search on it for the fun of it).\n\nSee the contrasting beliefs of the Eastern Orthodox, Oriental and Catholic Churches on this point.  They are far more coherent.

Catholics can be categorized as Christians. The difference is the Catholics believe that their church (via the Pope) has absolute authority in matters of spirituality. The rest of the Christian world (Protestants) believes that spiritual authority comes from the Bible alone.

Arianism was one of the early heresies of the church.  The way I understand it, there was a great debate in the early church about both Christ's humanity and his divinity.  The orthodox view that developed out of these disagreements was a balanced view that stated both the humanity and the divinity of Christ without emphasizing one too much at the expense of the other.  Arius, whom you referenced in your question (couldn't follow the link), was probably the most notable proponent of a Christology that denied the divinity of Christ.  The Council of Nicaea in 325 addressed the controversy; the council resoundingly declared Arius's view heretical and adopted a creed still spoken today in many Christian churches that very clearly refers to the disagreement ("begotten, not made, one in being with the Father").
