An interpretation of The Creation of Adam gives insight into liturgical participation, especially of the priestly sort. At the center of this central picture of the Sistine Chapel’s ceiling are God’s and Adam’s fingers about to touch, putting the capstone on the Trinity’s visible creation. But these figures are not yet touching, and the space between them — and the power to fill it — begins to speak directly about priesthood. The adjoining panels in the chapel’s ceiling help us to see why.
