Contradiction with Matthew 10:14
This verse contradicts Acts 14:21 because it advises leaving a place if it rejects the message, while Acts 14:21 mentions returning to cities where they had previously preached.
Matthew 10:14: And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.
Contradiction with Matthew 28:19
This verse's directive to go and teach all nations contrasts with returning to specific cities as described in Acts 14:21.
Matthew 28:19: 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 6:11
Similar to Matthew 10:14, this encourages shaking off the dust from one's feet and moving on, conflicting with the return in Acts 14:21.
Mark 6:11: And whosoever shall not receive you, nor hear you, when ye depart thence, shake off the dust under your feet for a testimony against them. Verily I say unto you, It shall be more tolerable for Sodom and Gomorrha in the day of judgment, than for that city. [and: Gr. or]
Contradiction with Luke 9:5
Again, this verse advises departing from unwelcoming places, unlike the return strategy in Acts 14:21.
Luke 9:5: And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them.
Contradiction with John 4:44
Indicates a prophet has no honor in his country, while Acts 14:21 describes going back to previously visited places.
John 4:44: For Jesus himself testified, that a prophet hath no honour in his own country.
Contradiction with Acts 18:6
This verse mentions turning away from non-receptive audiences to seek others, as opposed to the return visits in Acts 14:21.
Acts 18:6: And when they opposed themselves, and blasphemed, he shook [his] raiment, and said unto them, Your blood [be] upon your own heads; I [am] clean: from henceforth I will go unto the Gentiles.
