Ephesians 3:9

"And to make all men see," saith he, "what is the dispensation of the mystery which from all ages hath been hid in God, who created all things." Angels knew only this, that "The Lord's portion was His people." And again it is said, "The Prince of Persia withstood me." So that it is nothing to be wondered at that they were ignorant of this; for if they were ignorant of the circumstances of the return from the Captivity, much more would they be of these things. For this is the gospel. "It is He that shall save," it saith, "His people." Not a word about the Gentiles. But what concerns the Gentiles the Spirit revealeth. That they were called indeed, the Angels knew, but that it was to the same privileges as Israel, yea, even to sit upon the throne of God, this, who would ever have expected? who would ever have believed? "Which hath been hid," saith he, "in God." This "dispensation," however, he more clearly unfolds in the Epistle to the Romans. "In God," he continues, "who created all things by Jesus Christ." And he does well to say "by Jesus Christ;" forasmuch as He who created all things by Him, revealeth also this by Him; for He hath made nothing without Him; for "without Him," it is said, "was not any thing made."

"To preach unto the Gentiles the unsearchable riches of Christ." If His "riches are unsearchable," and that too after his appearing, much more is His essence. If it is still a mystery, much more was it before it was made known; for a mystery he calls it on this account, because neither did the Angels know it, nor was it manifest to any one else.
