Isn't Jesus one in being with the Father or are you asserting that He is a completely separate being or entity?
Why are you arguing with that? Was Jesus wrong? Did He lie about it?
Aren't Catholics the ones who hold the words of Jesus in higher esteem than the rest of the NT? How can the words of men in whatever creed they quote negate what Jesus Himself said?
Here they are again, for the (apparently) Scripture reading challenged....
John 12:47-48 "As for the person who hears my words but does not keep them, I do not judge him. For I did not come to judge the world, but to save it. There is a judge for the one who rejects me and does not accept my words; that very word which I spoke will condemn him at the last day.
