Jeremiah 1:4-5, 17-19 Homily Notes
From Reading Cornelius Lapide
--Tradition sees in Jeremiah a type of Jesus Christ: 1) formed in the womb is Jesus was found in the womb of the Blessed Virgin Mary by the power of the Holy Spirit; 2) Jeremiah is made a prophet to the nations, just as it says of Jesus Christ in the Isaiah 51:16 "I have put my words in your mouth", etc.... or Isaiah 49:6 which says of Christ "behold I have given you as a light to the nations"
-- the "word" that happened to Jeremiah... a way of referring to all that the Lord spoke to Jeremiah for 41 years
-- "I knew you" means "I approved of you with an approbation by which I knew ahead of time and predestined you, form view, created you a man and a minister of my words".... Rom 11:2 "God hath not cast away his people, which he foreknew."
--"I sanctified you"... sanctificavi te... dealt with your original sin even while you were in the womb, as with John the Baptist, so with Jeremiah... consecrated you for my work as a holy Prophet, separated you from things profane... "from all eternity I knew you, love you, predestined you to holiness and prophetic duty"... an infusion of sanctifying grace
