Contradiction with Matthew 5:44
While Philemon 1:2 mentions greetings to Philemon’s household with a tone of fellowship and brotherhood, Matthew 5:44 speaks about loving your enemies, which may imply a broader love that contradicts the specificity of a household-focused greeting.
Matthew 5:44: 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;
Contradiction with Luke 14:26
Philemon 1:2 is addressed with warmth towards a family and close associates, whereas Luke 14:26 challenges followers to put Jesus above familial relationships, which may seem to downplay the familial affection seen in Philemon 1:2.
Luke 14:26: If any [man] come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
