25 including the works of the church fathers, especially Justin Martyr. I have read his 'Dialogue with Trypho" many times. Justin lived around 150ad. Just at the time the church was moving into an interesting history. The apostles had been dead and gone for about 30 years by this time, and the church was changing.
So without a biblical foundation, the whole church was collapsing. So Justin tells us that:
1) God and His Son Jesus are 2 separate and distinct beings.
2) That God did not create things from nothing.
3) That the OT has been changed to try to eliminate prophecies of Jesus Christ.
Among other things. But very interesting.
I also studied some of the words of Origen who taught:
1) the Bible was changed by well meaning men by mistake, and evil men on purpose, and proved it with the Hexapla.
2) baptism is essential to being saved.
3) must be baptised of water to be able to receive the Holy Spirit.
Tertullian says:
1) Without baptism salvation is attainable to none.
Cyprian says:
1) Unless we receive baptism, you cannot be saved.
2) hands are layed on the head for the reception of the Holy Spirit.
The church fathers are all over the place when it came to discussing doctrine, but the early church fathers knew about the importance of being baptized of water and of the Holy Spirit and how it should be done. And other important topics that Jesus restored to the Church of Jesus Christ of Latter-day Saints from the Church of Jesus Christ of First-century Saints.
