“Btw, where does the Bible teach that baptism:
1. Is done out of obedience?”
It is commanded of believers. If they don’t follow the command, they are not being obedient. I am not aware of any church that sneaks up on people and throws them into a baptismal pool
“2. Is a testimony for others?”
They stand in the presence of others and follow the Lord by obediently being baptized with water.
“Both statements are foreign to the Scriptures.”
You need to read more FRiend.
It is commanded of believers. Yes, but that is not a reason we are to be baptized. Believers are commanded to keep the Apostolic Tradition, and look how many today reject it but privately interpreting the Scriptures. NO ONE was ever told in the Scriptures to be baptized as an act of obedience.
Is a testimony for others. Again, no one was ever told to be baptized as a testimony to others. Who was Paul standing before when he was baptized to wash away his sins? What about the eunuch in Acts, who was his baptism a testimony to?
Biblically, we are baptized to:
1. Remit sins
2. Receive the Holy Spirit
3. Be placed into Christ.
Once the Biblical reasons for baptism were rejected in the 16th century, other reasons had to be invented for baptism, hence obedience and public testimony.
I am willing to read any Scriptures you can provide where anyone was told to be baptized out of obedience or as a testimony. I have never come across any such verses, and I suspect neither have you.
