Patristic A.D. 735
“The master of the house is Christ, who since as very God He is every where, is already said to be within those whom though He is in heaven He gladdens with His visible presence, but is as it were without to those whom while contending in this pilgrimage, He helps in secret. But He will enter in when He shall bring the whole Church to the contemplation of Himself. He will shut the door when He shall take away from the reprobate all room for repentance. Who standing without will knock, that is, separated from the righteous will in vain implore that mercy which they have despised. Therefore it follows, And he will answer and say to you, I know you not whence ye are.”
