From "Jesus of Nazareth," by Joseph Klausner, a Jew writing for Jews
(please see especially the third paragraph down):

In the mouths of the Jews and heathen opponents of Christianity, these
stories were turned into subjects of ridicule: all the noble
qualities of Jesus which the disciples had found in him were twisted
into defects, and all the miracles attributed to him, into horrible
and unseemly marvels.

It should be noted that the earliest of these stories, of which we
will speak later, date from a time before the latest of the surviving
Gospels reached their present form and before they were accepted as of
canonical rank; yet these Talmud stories seem as though they are
deliberately intended to contradict events recorded in the Gospels:
the selfsame facts are perverted into bad and blameable acts.

For example, the Gospels say that Jesus was born of the Holy Spirit,
and not of a human father; the Talmud stories assert that Jesus was
indeed born without a father, yet not of the Holy Spirit but as the
result of an irregular union. The Gospels say that he performed signs
and wonders through the Holy Spirit and the power of God; the Talmud
stories allow that he did indeed work signs and wonders, but by means
of magic.

In the Gospels Jesus' opposition to the Pharisees and Scribes and
their "rote-learning precepts of men," and his own teaching as what
constitutes true religion, are held up for admiration; the Talmud,
however, avers that he was a "sinner in Israel" and a "scoffer against
the words of the wise."
