Goodness, where do I begin:
The earliest agreements (100-300):
- Early Christian’s believed and refered to the Scriptures as authority.
- The early Christians believed that people must trust and believe in Christ.
- The early Christians believed that living a Christian life was an essential part of what it means to be Christian that separated them from a Pagan society.
- The early Christians believed in the communion of the saints.
- The early Christians believed in the Apostle’s Creed.
- The early Christians believed the Christ was the Messiah (although it took time for them to fully realize what that meant).
- The early Christians believed in the Holy Spirit.
- The early Christians believed that one must submit to local bishops (although, this does not imply absolute authority, just authority)
- The early Christians were primarily concerned with pastoral care among their flock (i.e. Ignatius and Clement), and did not have the oppertunity to develop much in doctrinal areas.
- The early Christians believed that Christ died and rose again.
- The early Christians believed that Christ was coming again (most were premillenial).
- The early Christians believed in the grace of God.
- The early Christians believed that God is revealed in the truth of most philosophies (except for some people’s interpretation of Turtullian.
- Early Christian’s believe in an educational institution the Catechemenate.
- The early Christians believed in water baptism as an initiation rite of passage that involved three stages (protecting against mere professors, and those who had been converts from other religions and did not understand Christianity).
- That Christ was a man and divine.
What the earliest Christians believed that both Catholics and Protestants don’t:
- That Christ was ontologically subordinate to the Father (although I believe that this was done out of ignorance since the early Church had not dealt with this issue yet. Martyr and Origen.
- That man will is totally free and able to choose God without aid.
- Premillennialism (although some Protestants do believe this).
- That the atonement was a price paid to Satan, not God (understandable since they did not have time to deal with these doctrinal issues and they were heavely influenced by Greek dualism).
What the earliest Christians did not have any conception of (even in seed form) that either Protestants or Catholics believe today:
- Marian theology (assumption, co-redemtrix)
- Prayers to the saints
- Rapture
- Seven distinct Sacraments
- Definition of the sacraments as drawing form a deposit of Grace purchased by Christ.
Debatable Points that are hard to determine
exactly what they believed:
- Theology of Baptism (i.e. the affects of baptism)
- Theology of the eucharist (i.e. the affects of the eucharist)
- That Scripture is the ultimate authority.
- That there was two deposits of faith, both equal.
Certianly, all would agree, none of these existed *in the current articulations in which they exist today no matter what tradition you are from. *This does not make them wrong. It was understandable since they were more concerned with pastoral guidence and doctrines are only articulated in the midst of controversy.
These are all off the top of my head and I know that there are many more.
