Catena Aurea · Johannesevangelium 14
Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world? Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him. He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father’s which sent me. These things have I spoken unto you, being yet present with you. But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you.
(Hom. xxx.) Into some hearts He cometh, but not to make His abode with them. For some feel compunction for a season and turn to God, but in time of temptation forget that which gave them compunction, and return to their former sins, just as if they had never lamented them. But whoso loveth God truly, into his heart the Lord both comes, and also makes His abode therein: for the love of the Godhead so penetrates him, that no temptation withdraws him from it. He truly loves, whose mind no evil pleasure overcomes, through his consent thereto.
