You know that part in the Apostle’s Creed about “descended into hell”? Hell as in Sheol? That part’s about Jesus going to the Limbo of the Patriarchs to preach to our forefathers (and.foremothers!) and to bring them out.
Some people associate this with the Jewish “saints” who were resurrected at this time; so it’s even possible that Adam and Eve traipsed alive around Jerusalem. The more usual view is that this only happened to more recently dead people as a foretaste of the bodily resurrection after the Last Judgment; most of the Patriarchs and Matriarchs et al, simply had their souls released to heaven. I don’t think anybody’s said anything definitive either way.
(But Adam, Eve, and many other Biblical figures are indeed counted as saints by the Catholic Church, and had feasts assigned in the older universal calendars. The feast day of St. Adam and St. Eve is on Dec. 24th; and yes, that’s in honor of Christmas, the celebration of God’s Incarnation as a man and thus the New Adam.)
The Harrowing of Hell, as Jesus’ descent into hell was called more commonly, used to be a very big deal in art and poetry and drama. You’ll see Jesus breaking down the gates of limbo and standing on top of some demon schmuck, while ushering out his ancestors and the rest of the blessed dead… it’s fun stuff.
Anyway, as I said, it’s in the Apostles’ Creed, which most Christian denominations accept. Unfortunately, it’s an ancient teaching that’s a bit too dramatic for those of our brothers and sisters who prefer their theology boring, irrelevant, unmiraculous, and undemanding. So most Christians don’t hear about it much.
So encourage your priest or preacher to look into it! Good stuff!
