Contradiction with Matthew 5:14-16
These verses encourage believers to be the light of the world and not hide their good deeds, which contradicts Jesus' instruction to the healed man in Mark 1:44 to tell no one.
Matthew 5:14-16: Ye are the light of the world. A city that is set on an hill cannot be hid.
Contradiction with Matthew 28:19-20
The Great Commission commands spreading the teachings of Jesus, contrasting Mark 1:44 where Jesus tells the man to say nothing to anyone.
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 Mark 5:19
Jesus tells a man healed of demonic possession to go home and tell his friends what God has done, opposing the instruction in Mark 1:44 to say nothing.

Contradiction with Luke 8:39

Contradiction with John 4:29
The Samaritan woman at the well goes and tells her town about Jesus, an action that goes against the command in Mark 1:44 to keep the miracle quiet.
John 4:29: Come, see a man, which told me all things that ever I did: is not this the Christ?
Contradiction with Acts 1:8
The verse commissions believers to be witnesses for Jesus everywhere, which is opposite to Jesus’ instruction for silence in Mark 1:44.
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]
