At that time it was not yet everywhere. Yet in the principal places it had already been firmly sown, and only time was needed for it to gain strength and grow.
This is exactly what happened, as the Apostle immediately says. “And is bearing fruit and increasing, as also among you.”
It is in you, as also in all the world. And in all the world it bears fruit and increases, as also among you.
“It abides everywhere, rules everywhere, and stands everywhere. And it does not merely stand, but bears fruit and increases.
It bears fruit by works. It increases by receiving many. But neither would happen if it did not remain unchanged. Plants too become thick when they stand firmly in the ground,” say Saint Chrysostom and blessed Theophylact.
The Apostle expressed himself in such a way as to give the thought that fruitfulness and growth are inherent properties of the Gospel.
Let it only be planted in a few hearts somewhere, and from there it will itself begin to bear fruit and expand.
These qualities can be outlined in this way. It is fruitful: it enlightens, sanctifies, and blesses. It increases: it grows in depth, height, and breadth.
It grows inwardly in each person, and outwardly in drawing more and more persons.
“As also among you.” “By praises he wants to anticipate them and take possession of them, so that later, even if they wished to depart, they would be ashamed,” say Saint Chrysostom and blessed Theophylact.
This also gave firmness. If they had already received fruit, what sense would there be in leaving something manifestly fruitful and rushing toward something new and unknown?
“From the day you heard and understood the grace of God in truth.” “The Gospel bears fruit and increases in you from the day you heard it and came to know the grace of God.
How? Not in appearance, not in deceptive words, but in truth, that is, by the action of signs and wonders,” says blessed Theophylact.
“And is it not hard now to begin disbelieving something that immediately, at the very beginning, showed its power?” says Saint Chrysostom.
They heard the Gospel and believed. Having believed, they received the grace of God. By its enlightening, sanctifying, and blessing action in their hearts, it gave each person tangible understanding.
They understood that the faith proclaimed by the Gospel was undoubtedly true. From then on, you did not cease bearing fruit and increasing.
You were both being perfected in spirit within yourselves and drawing others to the faith. How many of you were there at first?
Epaphras and Philemon with his household. But now among you there are many believers, and beyond you also in Laodicea and Hierapolis.
All are from one seed. And all of you are wise, holy, and skilled in every work. All this is still growing and will continue to grow.
How can one cease to believe something so fruitful and increasing? The Apostle wanted to impress two images on their mind.
These were the universality of the faith and its beneficence, the strongest indications of the truth of the faith.
Saint Chrysostom says: “You see that the whole universe is turning to the faith. And is it necessary to speak of what is happening among others?
What is happening among you is convincing even without that. For you understood the grace of God in truth, that is, from the deeds themselves.
Thus faith is confirmed by these two things: that all have believed, and that you have experienced it.”
“You understood the grace of God in truth” can mean this: by the deed itself and from experience you came to know how great the grace is that the Gospel brings to those who receive it with faith.
