What makes you say that?
Do you know on what basis they make this argument? Can you point to anything that would support that contention or are you just saying, “So and so says”?
For example this from the “Answers” source:
” Most scholars question Paul’s authorship of six more biblical letters attributed to him: Ephesians, Colossians, 2 Thessalonians, 1 Timothy, 2 Timothy and Titus. They differ from his other epistles in style, viewpoint and vocabulary. Their unknown authors may have identified with Paul’s school of thought or hoped to invoke his authority...”
Who are these “most scholars”? How do those six letters of Paul differ from the others, what style, viewpoint, vocabulary?
I can't believe you have any idea and I can't see any reason to think you've actually made any investigation at all to find out since you reply to any question is a web site.
For example the letter to the Colossians Paul both opens and closes naming himself as the author though he may have had a secretary do the actual penning. But from wikipedia,
“The authenticity of Colossians has been questioned[46] on the grounds that it contains an otherwise unparalleled description (among his writings) of Jesus as ‘the image of the invisible God,’ a Christology found elsewhere only in John’s gospel.”
Then why not question John's writing too? That Paul agrees with John proves he didn't write Colossians? Please! This is scholarship?
Further from that wikipedia citation on the book of Ephesians:
“Ephesians is a very similar letter to Colossians, but is almost entirely lacking in personal reminiscences. Its style is unique. It lacks the emphasis on the cross to be found in other Pauline writings, reference to the Second Coming is missing, and Christian marriage is exalted in a way which contrasts with the reference in 1 Cor. 7:8-9.”
Ephesus was was an extremely wealthy city with the temple of the goddess Artemis, it was also a very immoral city and Paul found it necessary to make clear God's righteous moral laws as in chapter 5.
Part of Christian morality Paul pointed out was proper love and treatment of marriage mates. On the other hand what Paul wrote in 1 Cor. 7:8,9, was his own opinion on the desirability of widows remarrying
and he said it was his opinion not a command from God.. There is no contrast or conflict to had there.
So the great mind at wikipedia either doesn't read or doesn't even the most simple Scriptures.
So too your source, the rabbi, who impeached himself but had you looked beyond his saying what seemed
to support your view you would have known his views of the Last Supper and general bias.
Repeating opinions is easy, and not the same as having convictions, that's what makes me say that.
