48. And since you are worthy to be compared not now with men but with heavenly beings, whose life you are living on earth, receive from the Lord the precepts you are to observe: “Set Me as a signet upon thine heart, and as a seal upon thine arm;” Cant. viii. 6. that clearer proofs of your prudence and actions may be set forth, in which Christ the Figure of God may shine, Who, equalling fully the nature of the Father, has expressed the whole which He took of the Father’s Godhead. Whence also the Apostle Paul says that we are sealed in the Spirit; Eph. i. 13. since we have in the Son the image of the Father, and in the Spirit the seal of the Son. Let us, then, sealed by this Trinity, take more diligent heed, lest either levity of character or the deceit of any unfaithfulness unseal the pledge which we have received in our hearts.
