John the Apostle
John 6:47BSB·traditional attribution

Truly, truly, I tell you, he who believes has eternal life.

John Calvin Reformed @genevareformer

47. He who believeth in me. This is an explanation of the former statement. For we are taught by these words that it is when we believe in Christ that God is made known to us; for then do we begin to see, as in a mirror, or as in a bright and lively image, God who was formerly invisible.

Matthew Henry Presbyterian @wholebiblehenry

Whether this conference was with the Capernaites, in whose synagogue Christ now was, or with those who came from the other side of the sea, is not certain nor material; however, it is an instance of Christ's condescension that he gave them leave to ask him questions, and did not resent the interruption as an affront, no, not from his common hearers, though not his immediate followers.
