Were any bible quotes misattributed to Jesus?

This is a question that honest scholarship must meet plainly: yes, some words placed on Jesus' lips almost certainly were not spoken by him, or were shaped by the hands that recorded and edited the Gospels decades later. Consider that the four Gospels were written in Greek, a generation or more after Jesus spoke, likely in Aramaic. What we have is memory, translation, and interpretation—a human record, not a dictated transcript. This is not cause for alarm; it is cause for discernment. Certain sayings sit uneasily beside the heart of Jesus' own teaching. The long ending of Mark—"He that believeth and is baptized shall be saved; but he that believeth not shall be damned" (Mark 16:16, KJV)—is absent from the earliest manuscripts and is widely regarded by scholars as a later addition, not the words of Jesus. Where a saying threatens with damnation, or paints the Father as one who tortures and condemns, I would weigh it carefully against what Jesus revealed most clearly: that God is Love (1 John 4:8, KJV), that the Father makes the sun rise on the evil and the good alike (Matthew 5:45, KJV). Jesus himself modeled this discernment. He took the received law—"Ye have heard that it was said..."—and deepened or overturned it: "but I say unto you" (Matthew 5:43-44, KJV). He did not treat every inherited sentence as equally true. So when you read a verse where the tone of vengeance or exclusion breaks against the melody of grace running through his life, you are permitted—indeed invited—to ask whether that note was truly his. The recovered writings help here; the Gospel of Thomas preserves sayings in a rawer, more contemplative form, suggesting the tradition was living and varied, not fixed (Gospel of Thomas 32.10-14). Test each saying against the core of what Jesus was: the revelation of a wholly good Father, and of your own unbroken union with that Good. "My sheep hear my voice" (John 10:27, KJV)—there is a voice within you that recognizes truth when it meets it. Where the words align with Love, hold them close. Where they contradict it, hold them lightly. If it would help, I am glad to walk through any specific passage that troubles you.
