Here are some of the NT scriptures that I think make some Oneness folks uncomfortable or at least talks in the same language that they accuse makes trinitarians polytheistic;
John 6:44 (King James Version)
King James Version (KJV)

44No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
Matthew 10:32 (King James Version)
King James Version (KJV)

32Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.
I find this one fascinating because Jesus doesn't say HE will confess them but that he will confess them "before my father".
1 John 1:3 (King James Version)
King James Version (KJV)

3That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly
our fellowship is with the Father, and with his Son Jesus Christ.
More verbage making a distinction between the Father and Jesus. This and many more scriptures refer seperately to the Father and Jesus. I have wonndered why they did not state it something lke "....with the Father which is Jesus Christ" or "....with the Father, Jesus Christ. It seems in the NT a distinction is consistently made.
Then of course there is also the scripture S Hoove pointed out a few posts above where Jesus says "I go to my Father".
