I am a saved believer in the finished work of Christ. I don't care if Paul uses the wording, Ananaisis, or Ruford Welthorpe. God's word is my guide, I believe in the literal return of Christ, and I believe that we in this present age of grace, are members of the Church the Body of Christ. You can call it smvoice's creed if you wish. I don't care. I DO care about the Gospel of the Grace of God. If this commission was given to Paul to give to this present age, then that's the way it is. Don't like it? Take it up with God. He chose.
The number of errors is large but finite.Most of them cropped up in the first few centuries. In attempting their refutation, the Father classified them with the names of their founders (Arianism, Pelagianism) or the names of their principle doctrines (Docetism, Adoptionism, Monothelitism.) Learning them was part of Church History in seminary.
