As for the rest of this article, it's the usual Catholic rubbish that I'm seen on this issue dozens of times before. Appealing to 3rd century authorities (which we don't even know were really majority viewpoints, anywise) as if they were apostolic, while taking verses of Scripture completely out of context while redacting later Catholic doctrine back into them.
Might convince those who are already Catholic, but not very persuasive to anyone who actually knows anything about the Scriptures.
“Unless you are baptized by the Holy Spirit, you shall not enter the Kingdom of God>”
Not just a water baptism, but a baptism of the Father, Son and Holy Spirit just as recorded in Matthew when Jesus gave instruction to the apostles and disciples gathered before his Ascension into heaven.
Exactly.
