“What you reference are not complete texts but small ‘snippets’. “
Polycarp: “... as it is said in these Scriptures “be angry but sin not” and “let not the sun go down on your anger”.
Eph 4:26 Be ye angry, and sin not: let not the sun go down upon your wrath:
So, was Polycarp just quoting an oral tradition about scriptures he had never even read?
Your arguments are utterly ridiculous.
He was repeating what he heard. Were you to reference an entire letter, as recited by Polycarp, it would be different. But these various bits and pieces were passed along and communicated through oral tradition. There were certain letters written to particular churches but you have yet to cite one.
