Luke11:1 "And it came to pass, that, as he was praying in a certain place, when he ceased, one of his disciples said to him, Lord, teach us to pray, as John also taught his disciples.12 And he said unto them, When you pray, say, Our Father who is in heaven, Hallowed be your name. Your kingdom come. Your will be done, as in heaven, so on earth........"
Sounds like Mary might have taught Jesus the Our Father! [Nah, I don't think so]
