What you will find, to be a Judaizer, according to the Bible, actually means one who does and teaches their own way and traditions instead of the Bible. A Judaizer does not teach or obey the Laws of God.  Today this can apply to many traditional Christian churches just as it applied to the Pharisees 2000 years ago, and apply also to Modern Judaism of today.

Jesus (Y’shua) siad in Matthew 5:17,19
“Do not think that I have come to abolish the Law … 
whoever does them and teaches them will be called great in the kingdom of heaven.”

Jesus (Y’shua) said to the Pharisees (“The Judaizers”) in Mark 7:6-8
“This people honors me with their lips, but their heart is far from me;
in vain do they worship me, teaching as doctrines the commandments of men.
You leave the commandment of God and hold to the tradition of men.”
