Tractates on the Gospel of John

² We are therefore to understand that he who loves has already the Holy Spirit, and by what he has becomes worthy of a fuller possession, that by having the more he may love the more. Already, therefore, had the disciples that Holy Spirit whom the Lord promised, for without Him they could not call Him Lord; but they had Him not as yet in the way promised by the Lord. Accordingly they both had, and had Him not, inasmuch as they had Him not as yet to the same extent as He was afterwards to be possessed.

They had Him, therefore, in a more limited sense: He was yet to be given them in an ampler measure. They had Him in a hidden way, they were yet to receive Him in a way that was manifest; for this present possession had also a bearing on that fuller gift of the Holy Spirit, that they might come to a conscious knowledge of what they had. It is in speaking of this gift that the apostle says: “Now we have received, not the spirit of this world, but the spirit which is of God, that we may know the things that are freely given to us of God.” For that same manifest bestowal of the Holy Spirit the Lord made, not once, but on two separate occasions.

For close on the back of His resurrection from the dead He breathed on them and said, “Receive the Holy Spirit.” And because He then gave [the Spirit], did He on that account fail in afterwards sending Him according to His promise? Or was it not the very same Spirit who was both then breathed upon them by Himself, and afterwards sent by Him from heaven? And so, why that same giving on His part which took place publicly, also took place twice, is another question: for it may be that this twofold bestowal of His in a public way took place because of the two Commandments of love, that is, to our neighbor and to God, in order that love might be impressively intimated as pertaining to the Holy Spirit.

And if any other reason is to be sought for, we cannot at present allow our discourse to be improperly prolonged by such an inquiry: provided, however, it be admitted that, without the Holy Spirit, we can neither love Christ nor keep His commandments; while the less experience we have of His presence, the less also can we do so; and the fuller our experience, so much the greater our ability. Accordingly, the promise is no vain one, either to him who has not [the Holy Spirit], or to him who has.

For it is made to him who has not, in order that he may have; and to him who has, that he may have more abundantly. For were it not that He was possessed by some in smaller measure than by others, St. Elisha would not have said to St. Elijah, “Let the spirit that is in you be in a twofold measure in me.”
