Disciples don’t kill Disciples.
Christians have always killed Christians.
Matthew 5:38-39 (KJV) 38 Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth: 39 But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.
Matthew 5:43-48 (KJV) 43 Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. 44 But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; 45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. 46 For if ye love them which love you, what reward have ye? do not even the publicans the same? 47 And if ye salute your brethren only, what do ye more [than others]? do not even the publicans so? 48 Be ye therefore perfect, even as your Father which is in heaven is perfect.
Matthew 26:52 (KJV) Then said Jesus unto him, Put up again thy sword into his place: for all they that take the sword shall perish with the sword.
Luke 3:14 (KJV)
And the soldiers likewise demanded of him, saying, And what shall we do? And he said unto them, Do violence to no man, neither accuse [any] falsely; and be content with your wages.
