Today - reading middle chapters of Epistle to the Hebrews (1-year Genesis to Revelation plan)

Just as there is a Law which contains a "shadow of the good things to come" (Hebrews 10:1) which have been revealed by the law proclaimed in accordance with truth, so als the gospel, which is thought to be understood by all who read it, teaches a shadow of the mysteries of Christ. The eternal gospel (Revelation 14:6) which would properly be called a spiritual gospel, clearly presents both the mysteries presented by Christ's words and the things of which his acts were symbols to those who consider "all things face to face" (Proverbs 8:9) concerning the Son of God himself -- from Book 1 of Origen's Commentary on the Gospel of John -- relating to the Law and the Gospel.
