Contradiction with Matthew 28:19-20
Jesus instructs his disciples to spread his teachings to all nations, which contrasts with the temporary command of keeping the event secret in Mark 9:9.
Matthew 28:19-20: Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: [teach...: or, make disciples, or, Christians of all nations]
Contradiction with Acts 1:8
Jesus tells his apostles they will be his witnesses to the ends of the earth, contradicting the earlier instruction to keep silent about their experiences.
Acts 1:8: But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. [power...: or, the power of the Holy Ghost coming upon you]
Contradiction with Mark 16:15
Jesus commands to preach the Gospel to every creature, which opposes the restriction in Mark 9:9.
Mark 16:15: And he said unto them, Go ye into all the world, and preach the gospel to every creature.
Contradiction with John 4:29
The Samaritan woman immediately shares her encounter with Jesus, unlike the secrecy in Mark 9:9.
John 4:29: Come, see a man, which told me all things that ever I did: is not this the Christ?
Contradiction with Luke 8:39
Jesus tells the healed demoniac to proclaim what God did for him, going against the instruction to not tell anyone initially.
Luke 8:39: Return to thine own house, and shew how great things God hath done unto thee. And he went his way, and published throughout the whole city how great things Jesus had done unto him.
Paradox #1
While Mark 9:9 involves Jesus instructing his disciples not to tell anyone about what they have seen until after his resurrection, some consider this instruction as a contradiction or inconsistency when compared to other parts of the Bible where Jesus tells people to proclaim his miracles or identity immediately. However, a common interpretation is that Jesus wanted to control how and when his mission and identity were publicly revealed to suit a particular divine timing, rather than any real contradiction.
