Wendelin's Christian Theology is a gem. His manner of encapsulating theological truth in concise and clear statements is noteworthy. Under the priestly office of Christ he observes how Christ is priest, sacrifice, and altar all at once. This is a brilliant example to show how Christ is all in all to us.
He writes,
Theologians note, that in the priestly office Christ was priest, sacrifice, and altar. Priest, according to both natures, Hebrews 5:6. Sacrifice, properly according to His human nature, 1 Peter 4:1; Colossians 1:22, even if its principal efficacy was depending upon the divine nature. Altar, according to His divine nature, Hebrews 9:14; 13:10. Accordingly, the altar sanctifies the victim, Matthew 23:19. Christ, as God, sanctified Himself in His humanity:
(1.) By appointing His humanity as a sacrifice for sins.
(2.) By conferring merit and efficacy to His sacrifice, in order to acquire the remission of sins.
