Origen, on Heb 10:1

“For the law having a shadow of the good things to come, not the very image of the things; by the selfsame sacrifices which they offer continually every year, can never make the comers thereunto perfect:”

“We must also know that just as there is a "law" which contains a "shadow of the good things to come," which have been revealed by the law proclaimed in accordance with truth, so also the gospel, which is thought to be understood by all who read it, teaches a shadow of the mysteries of Christ.And that which John calls an eternal gospel, 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" concerning the son of God himself.”
