Oh, brother. There are quite many *apparent* contradictions in the Protestant canon, too. For instance: who are Jesus’ paternal grandparents? James, Revelations, and even the gospels also oppose your reading of Galatians, let alone the fact that Sirach is Old Testament, like all those laws of Moses which oppose Galatians.
Not even one contradiction in scripture.
>> who are Jesus’ paternal grandparents?<<
Not there is not. One simply doesn’t mention those in between. Same as those who said Jesus is the “son of David” when Jesus asked them.
>> Revelations, and even the gospels also oppose your reading of Galatians<<
Give me one example.
>> let alone the fact that Sirach is Old Testament<<
I gave you the Old Testament contradiction to Sirach.
>> like all those laws of Moses which oppose Galatians.<<
Not even one.
If you believe those statements then you must also admit that you don’t believe the infallibility of scripture which leaves you with nothing.
