Colossians 3:16 sent me looking for the psalms, hymns, and spiritual songs of Scripture, from the Song of Moses to the song of the Lamb. Who we worship matters, and so do where, when, why, and how.

He put the new covenant in His own blood into the hands of His friends, and we turned it into a sacrament. Read Hebraically, the cup is a covenant cut once and sealed forever, not a rite to be re-administered on a schedule by a professional. A sealed covenant cannot be re-sealed, and the covenant that retires the mediator was quietly rebuilt into a priesthood. Why I refrain, and what is still left at the table.
Pentecost is not the Church's birthday. It is the appointment HaShem set on His calendar before Israel had a calendar. Shavuot was already there. The Ruach was already moving. You are grafted in, not displaced.
