Mass indoctrination 1
If they teach you something that is not the doctrine of Jesus do not accept it. you should not accept the thing that is not in the bible. All the commandments if Jesus were written by the appostles, so anything that is not written by the appostles in the bible is not from Jesus.
His first doctrine is baptism, what is the proof that the first doctrine of Jesus is baptism, the apostle paul who the christians talk about was not a christian he was in the jewish religion and he mention that he persucuted the christian and made havoc of it. He was called by Jesus and when he was called the first thing that paul was told to obey when he was called in the church is to go and arise and be baptise in the name of Jesus says the bible and wash away thy sins calling upon the name of the lord. From Judaism where he persecuted the church of God he preach the faith which once he destroyed. So the very first doctrine fulfulled by paul is baptism because baptism is the formal act of joining the church in the bible.
