"*Huh. Imagine that. The Church's Teaching IS more understandable than yours. And, it has the advantage of being authoritative..."
Not MY teaching, Bub, Jesus Christ's teaching, in the Gospels.
What you gave me in a long and convulted medieval paragraph Jesus gave me in one single word: Gehenna.
Of course the Church gets around to being right, more or less, because the Holy Spirit doesn't let her err gravely on matters of faith and morals.
But no, that medieval paragraph is most certainly neither as understandable, nor as precise, as Jesus of Nazareth's one word: Gehenna.
Where in the Gospels did He who was w/o sin teach a concept of forgiveness that included punishment? Where did He act to forgive and punish, in accordance with such a concept?
