From Eden's Guardian to Sinai's Altar to the Cross and the Mass

Why did Israel need a priesthood and a sacrificial system at all? This session walks the full grammar of sacrifice God gave at Sinai — Passover, the priesthood, the blood of the covenant — and shows why it was real, but deliberately incomplete. Then we meet the strangest figure in the Old Testament: a priest-king named Melchizedek, with no recorded father or mother, whose order Christ's own priesthood claims a thousand years later.

Session 1 established the pattern — a real vocation given to Adam, corrupted at the Fall, slowly restored across salvation history — this session goes to the most unfamiliar territory for most modern Catholics: sacrifice and priesthood. Many participants attend Mass every week without a clear sense of why there needs to be an altar, a priest, or language of sacrifice at all, rather than simply a gathering for prayer and teaching. This session exists to close that gap. It also carries the heaviest payoff for understanding the Eucharist of any of the four sessions — by the end, participants should be able to explain, in their own words, why the Church insists the Mass is a real sacrifice and not a reenactment.
