There are creeds claiming that baptism causes Salvation and that by sprinkling babies who have no idea what's going on they can sucker in another schmuck. Conversion however results from a belief. Baptism follows on from that belief and clearly does not
cause the belief because catholic or Anglican baptism (of babies) very rarely results in Christian adults.
Acts 8: 5-6a, 26-29, 35-40
Then Philip went down to the city of Samaria, and preached Christ unto them. And the people with one accord gave heed unto those things which Philip spakeThe locations mentioned are shown on the map.
I've marked a line from Jerusalem to Gaza for reference.
And the angel of the Lord spake unto Philip, saying, Arise, and go toward the south unto the way that goeth down from Jerusalem unto Gaza, which is desert. And he arose and went: and, behold, a man of Ethiopia, an eunuch of great authority under Candace queen of the Ethiopians, who had the charge of all her treasure, and had come to Jerusalem for to worship, was returning and sitting in his chariot read Esaias the prophet. Then the Spirit said unto Philip, Go near, and join thyself to this chariot.The eunuch was puzzled by what he read.
Was it a prophecy that God was about to reproduce?
Philip explained this more fully.
Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus. And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized? And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God. And he commanded the chariot to stand still: and they went down both into the water, both Philip and the eunuch; and he baptized him. And when they were come up out of the water, the Spirit of the Lord caught away Philip, that the eunuch saw him no more: and he went on his way rejoicing. But Philip was found at Azotus: and passing through he preached in all the cities, till he came to Caesarea.
There are also people who claim that God does not produce children, or is incapable of doing so, or that the whole concept has nothing to do with any Israelite prophecy. These are false claims, not supported by Scripture. Obviously some heretic could write a different Gospel in which God did not have children and therefore did not have a son and therefore Jesus was not related to God. In such cases the heresy could be cooked up over a thousand years or so, complete with rewritten Scriptures, then after another thousand years the bogus material could be held up as bogus evidence for the bogus claims. But if that were the case, Philip would not be teaching The Truth and would not be endorsed by The Holy Spirit for his witness
that Jesus Christ is the Son of God. He would not have been sent to the eunuch with a false teaching and would not have been transported by The Holy Spirit to Azotus to continue his ministry.
But he was. The eunuch was saved. In this way we know that accepting Jesus as God's Son is the path to Salvation and that heretics are promoting garbage.
