What does the Bible say about religious hypocrisy?

The issue of religious hypocrisy is a significant theme in the Bible, particularly as illustrated by Judas Iscariot. Judas was an outwardly religious man who participated in ministry and performed miracles, yet his heart was filled with hatred for Christ. He displayed hypocrisy by pretending to honor Jesus while leading a mob to betray Him. This serves as a stark reminder that genuine faith is not merely about outward actions or knowledge of Christian teachings, but about a heart transformed by Christ. In Matthew 26:47-56, the presence of an insincere group of religious people illustrates how easily one can be misled by outward religious observance without a true relationship with Christ.
