Yet by calling himself one in the pains of birth, Saint Paul thereby expresses hope that the Galatians will again be born in the same spirit, after abandoning the deadening elements they had accepted.
The preceding speech gave the holy Apostle occasion to pour out before the Galatians all his parental love for them.
Remembering their zeal, he also remembered the perfection of faith and the good state in Christ Jesus the Lord in which they had been. They had now lost this state, or had begun to lose it.
His heart was compressed, his spirit was pained, and he kindled a most intense care for restoring them to their former rank.
So he cries out: little children! "Until Christ is formed."
By faith and baptism Christ was formed in them. They clung to Him, vividly contemplating deliverance by His death and the gift of new life by His grace.
By inclining toward Judaism, they allowed this brightly contemplated image of salvation in the Lord Jesus Christ to be darkened and disordered in themselves.
They also allowed the very likeness of Christ, given to souls in grace, to be diminished.
In instructing them, the Apostle raises them to their former contemplation of salvation in the Lord. He raises them to the reflection of the likeness of Christ in their souls.
Hoping for this, he labors. As he labors, he suffers pain like a woman giving birth.
He assures them that he will not cease suffering such pain until they again become as they were before.
This is the limit to which those zealous for the salvation of others must bring those they guide. Once they have brought them there, they can confidently say that they have set them on their feet.
The image of such strong love, breathed by these words, should have acted victoriously on the Galatians. This is what the holy Apostle seeks in the present section.
"See how troubled he is, and how anxious," says Chrysostom. "'My brethren,' he says, 'I beseech you'; 'my little children, for whom I again suffer birth pangs.'
"This is the voice of a mother who fears for her children. 'Until Christ is formed in you.'
"Do you see both fatherly love and sorrow worthy of an Apostle? Do you hear a cry far more bitter than the cry of one giving birth?
"You have shattered the image, he says, lost the high kinship, and changed the likeness. You need another birth, a new re-creation.
"Yet I do not cease to call you children, though you are miscarried and born before the time.
"Nevertheless, he does not speak so, but otherwise. He spares them and does not wish to harden them by laying wounds upon wounds.
"Skilled physicians do not heal those who have suffered a long illness all at once, but by intervals. They do this so as not to drive them into despondency and destroy them.
"So also does blessed Paul. These torments of his were more painful than bodily torments, as his love was stronger and their sin more serious.
"Yet, as I have always said and will not cease saying, even a small transgression harms and disfigures the whole beauty and image of God in man."
