Contradiction with Acts 15:1
This verse states that circumcision is necessary for salvation, which contradicts Galatians 2:3 where Titus, a Greek, was not compelled to be circumcised.
Acts 15:1: And certain men which came down from Judaea taught the brethren, [and said], Except ye be circumcised after the manner of Moses, ye cannot be saved.
Contradiction with Acts 16:3
This verse describes Paul circumcising Timothy, which contrasts with Galatians 2:3 where Titus was not circumcised.
Acts 16:3: Him would Paul have to go forth with him; and took and circumcised him because of the Jews which were in those quarters: for they knew all that his father was a Greek.
Contradiction with Genesis 17:10-11
This verse establishes circumcision as an everlasting covenant, whereas Galatians 2:3 implies it is not obligatory for Gentiles.
Genesis 17:10-11: This [is] my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised.
Contradiction with Exodus 12:48
This verse states that no uncircumcised person shall eat the Passover, conflicting with the notion in Galatians 2:3 that circumcision was not necessary for Titus.
Exodus 12:48: And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.
Paradox #1
The possible contradiction in Galatians 2:3 might arise when compared to the requirements of Jewish law regarding circumcision, especially in relation to other teachings in the New Testament that emphasize adherence to Jewish customs. This can create tension between following traditional Jewish laws and the new covenant of faith in Christ, reflecting early church debates on the necessity of these laws for salvation.
Paradox #2
Galatians 2:3 might seem inconsistent with the idea that the law of Moses, including circumcision, was necessary for all believers. This is because it shows that even though some early Christians believed Gentile converts needed to follow Jewish law, Paul argues it is not required for salvation. This reflects an early church debate over the necessity of following Jewish customs for non-Jewish Christians.
