728. VIII. TO THOSE WHO COME TO THE HOLY SUPPER WORTHILY IS LIKE A SIGNATURE AND SEAL THAT THEY ARE THE SONS OF GOD.
The reason why the holy supper is to those who come to it worthily like a signature and seal that they are the sons of God, is that as before said, the Lord is then present, and admits into heaven those who are born of Him, that is, the regenerate. The holy supper effects this, because the Lord is then present even as to His Human (for it has been shown above that in the holy supper the Lord is wholly present, and with His whole redemption); for of the bread He said, "This is my body; and of the wine, "This is My blood." Consequently He then admits them into His Body; and the church and heaven constitute His Body. When man is becoming regenerate, the Lord is indeed present, and through His Divine operation prepares man for heaven; but that man may actually enter he must present himself to the Lord; and as the Lord actually presents Himself to man, man must actually receive Him, not, however, as He hung upon the cross, but as He is in His glorified Human, in which He is present, the body of which is the Divine good and the blood of which is the Divine truth. These are given to man, and by means of them man is regenerated, and he is in the Lord and the Lord in him; and for the reason shown above, that the eating which is manifested in the holy supper is a spiritual eating. From all this rightly understood it is clear that the holy supper is like a signature and seal that those who come to it worthily are sons of God.
