It wasn’t the Christians in Rome who invented the “REAL baptism, RITUAL baptism” nonsense. They already knew what baptism was. They didn’t need Paul to say, “Now let me be clear about WHICH baptism I’m talking about here.”
There aren’t two baptisms, only one.
The bible proves you 300% WRONG...
Act 19:1 And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples,
Act 19:2 He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost.
Act 19:3 And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism.
Act 19:4 Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.
Act 19:5 When they heard this, they were baptized in the name of the Lord Jesus.
Act 19:6 And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.
Act 11:16 Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost.
Act 11:17 Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God?
There are 2 baptisms there...One with water, one without...
There are at least 7 baptisms in the bible...You of course will not find them in your catechism...That's why God gave us a bible...
