When did the Catholic Church start baptizing in the name of the Father Son and Holy Ghost?

Answer 1

I suppose that you can say that the Church began to baptize before it even began: with John the Baptist. "John the Baptist appeared in the wilderness, preaching a baptism of repentance for the forgiveness of sins" (Mark 1:4). He proclaimed that "I have baptized you with water; but he will baptize you with the Holy Spirit" (Mark 1:8). John then proceeded to baptize Jesus Himself, the very founder of Christianity. In Acts 2:37-42, it talks about the first converts to Christianity. It says "So those who received [Peter's] word were baptized, and there were added that day about three thousand souls" (Acts 2:41). What John said was also true, as when we are baptized we receive the Holy Spirit. "Repent, and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins; and you shall receive the gift of the Holy Spirit" (Acts 2:38). This is seen in a very visible way in the New Testament throughout all of the baptism testimonies. For example, in Acts 19:1-7: "While Apol'los was at Corinth, Paul passed through the upper country and came to Ephesus. There he found some disciples. And he said to them, "Did you receive the Holy Spirit when you believed?" And they said, "No, we have never even heard that there is a Holy Spirit."

And he said, "Into what then were you baptized?" They said, "Into John's baptism."

And Paul said, "John baptized with the baptism of repentance, telling the people to believe in the one who was to come after him, that is, Jesus." On hearing this, they were baptized in the name of the Lord Jesus. And when Paul had laid his hands upon them, the Holy Spirit came on them; and they spoke with tongues and prophesied.

There were about twelve of them in all. "

This has been the practice of the Catholic Church ever since the Great Commision in The Bible:

"Then the eleven disciples went away into Galilee, into a mountain where Jesus had appointed them. And when they saw him, they worshiped him: but some doubted. And Jesus came and spoke unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen."

(Matthew 28:16-20)
