>Actually, they didn’t. James, Peter and John explained/showed to Paul how many converts were zealous for the Law. They were converting heathens/non Jews to their religion at that time, which we today call Judaism. It had no name at that time.<
No, while Noahide laws may be seen being a requirement in Acts 15, Judaism did/does not preach, “Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.” (Acts 2:38) which Peter did to 3k+ Jews, and afterward to other Jews and Gentiles as well (Acts 10). This was Christianity whether it was called that or not, and it was in Acts 11:26 that that the name Christian was given to those who previously were seen as distinctive from Judaism. In Acts 21, James did give the well-meaning advice for Paul to go to the Jewish celebration of Pentecost, which only showed that what the apostles preached (Acts 15) was unacceptable to Judaism. And John was certainly not preaching Noahide laws as a means of salvation either.
Actually Yehoshua/Joshua/Jesus did preach that people needed to repent.
Matthew 3
2 And saying, Repent ye: for the kingdom of heaven is at hand.
Matthew 3:
8 Bring forth therefore fruits meet for repentance:
Matthew 4:17
From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.
Matthew 9:13
But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.
Matthew 11:20
Then began he to upbraid the cities wherein most of his mighty works were done, because they repented not: Mark 6
11 And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city.
12 And they went out, and preached that men should repent.
13 And they cast out many devils, and anointed with oil many that were sick, and healed them.
In Acts 10 which you happen to cite. Read closely. The Holy Ghost fell upon Cornelius prior to baptism, which just goes to show that baptism isn't necessary. Cornelius had already been found to be acceptable to G-d.
"Thou shalt love the Lord thy God" and "Love thy neighbor as thyself." (Deut) The "Two Tablets of the Law".
Acts 10:2 2 A devout man, and one that feared God with all his house, which gave much alms to the people (Second Tablet of the Law), and prayed to God alway (First Tablet of the Law) (KJV)
The First Tablet of the Law contained the commandments and obligations given to man concerning maintaining his relationship with God. In other words these commandments were "vertical"; between man and God. These commandments in the First Tablet of the Law dealt with man's relationship with God and when obeyed guaranteed man's continued acceptance with God. These Laws, or should I say "categories" of Laws were manifestations of man's Covenant stipulations with God whereby if observed "kept" man in good relationship with God within his respective Covenant. The Second Tablet of the Law contained the commandments and obligations given to man concerning man's relationship with man
Cornelius, not a Jew mind you, and not a convert to Judaism, keeping the Laws of God written on his heart which happens to be parallel to the Laws of Moses. Cornelius, the Gentile Godfearer mentioned in Acts 10, was a centurion at Caesarea and serves as a good example of what a Godfearer did religiously. First, he and his household were devout (the Greek word is eulabes) and Godfearing (Phoboumenos Ton Theon), which is a double adjective referring to him and his family which shows their exemplary lives characterized by Jewish norms and values.
2126 eulabes yoo-lab-ace' from 2095 and 2983; taking well (carefully), i.e. circumspect (religiously, pious):--devout.
2095 eu yoo neuter of a primary eus (good); (adverbially) well:--good, well (done).
Acts 9:36 Now there was at Joppa a certain disciple named Tabitha, which by interpretation is called Dorcas: this woman was full of good works and almsdeeds which she did (Second Tablet of the Law) (KJV)
Both Dorcas and Cornelius gave alms to the needy? This is taught by Judaism to result in a life that is honoring to God and the fruit of which earns one Eternal Life. Is it an accident that we see a resurrection from the dead of a person where the only thing mentioned is that she "did good works" and "gave alms" which just happens to be obedience to the Second Tablet of the Law? Is this just a coincidence?
This was Christianity whether it was called that or not, and it was in Acts 11:26 that that the name Christian was given to those who previously were seen as distinctive from Judaism.
Yehoshua was Jewish and he never left Judaism. His followers were Jewish as well.
James also told Paul to go purify himself with several men that had a vow on them. (nazarite) to show the people that he (Paul) still followed the Law!
