There is only one church that traces its heritage to 33AD. The Catholic Church. Scripture reveals that Church to be the one Jesus Christ built upon the rock of Saint Peter (Matt. 16:18). By giving Peter the keys of authority (Matt. 16:19), Jesus appointed Peter as the chief steward over His earthly kingdom (cf. Isaiah. 22:19-22). Jesus also charged Peter to be the source of strength for the rest of the apostles (Luke 22:32) and the earthly shepherd of Jesus' flock (John 21:15-17). Jesus further gave Peter, and the apostles and elders in union with him, the power to bind and loose in heaven what they bound and loosed on earth. (Matt. 16:19; 18:18). This teaching authority did not die with Peter and the apostles, but was transferred to future bishops through the laying on of hands (e.g., Acts 1:20; 6:6; 13:3; 8:18; 9:17; 1 Tim. 4:14; 5:22; 2 Tim. 1:6).
I will refrain from turning this thread into a RCC debate by agreeing that the Church established at Pentecost is the only true Church of Christ.
The Roman Catholic Church bears NO RESEMBLANCE to the church we read about in the New Testament.
