As that latter act is altogether unfitting, for “what agreement has the temple of God with idols,” so it is altogether unfitting when any one of you, through participation in paganism, brings something pagan into his soul.
For God graciously wills to dwell in that soul.
Chrysostom says: “Why do you, who bear God within yourself, run to idols, with which God has nothing in common?
“Is such an act worthy of excuse? Consider who lives in you and dwells with you.”
Having set forth such a series of opposites, the Apostle, as though taking believers by the hand, leads them away from everything pagan.
Since the summit of all distinctions between the believer and the unbeliever is true communion, living communion with the living God, the Apostle fixes special attention on this advantage.
He proves it by prophecies and through them depicts it from various sides.
The testimonies cited from the Old Testament are not read word for word in Scripture as Saint Paul cites them.
Rather, he gathered them from different places and joined them into one harmonious speech.
You, he says, are temples of the living God. And that this is so, hear what God promised Israel.
“I will dwell in them and walk among them,” “that is, I will dwell in these temples and walk in them, thereby showing His great good pleasure toward them” (Chrysostom).
“And I will be their God, and they shall be My people” (Lev 26:12). I am their God; they are My people.
In this, communion is expressed from God’s side. But when God proclaimed this to that people, and that people received it into their heart, they too came to have God as their God.
They came to have themselves as God’s people. In this is communion from the side of men.
So it was in Israel, the type of believers, and that communion was typological. It all took place outwardly.
True communion with God was accomplished by the Lord and Savior, first hypostatically in His own Person, and then graciously and morally in all believers.
All believers, becoming one with the Lord, become one with God truly and essentially.
The Lord Himself prayed thus: “That they all may be one, as You, Father, are in Me, and I in You, that they also may be one in Us” (Jn 17:21).
And the Lord’s prayer becomes reality in every believer. This is accomplished not nominally, but in actual deed.
Believers are regenerated by the grace of the Holy Spirit. They become pure through the rejection of the passions of self-pleasing and through the reception of all virtues.
They are a ready and God-befitting temple for God. He also dwells in them.
Dwelling in them, He leads them along the paths of life, or walks in them, as of old the pillar of cloud walked among Israel.
What took place outwardly in ancient Israel takes place inwardly in the new Israel, in souls and hearts.
For the Lord says, “If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our abode with him” (Jn 14:23).
