Therefore the believer who imitates Christ becomes (as far as he is permitted) the same as Christ whom he imitates. Whoever claims to abide in Christ, says John, must walk as Christ himself walked.
Human beings are conceived and given shape by their mothers, and once they have taken shape, their mothers go into labour and give them birth; so we may wonder what is meant by I must go through the pain of giving birth to you all over again, until Christ is formed in you. We can take the birth-pangs as meaning the anxiety he felt over them, that they should be born in Christ; or again, that he is suffering because he sees them surrounded by dangers that could lead them astray. The care and worry he feels, which he compares to the pangs of giving birth, may last until they are fully mature with the fullness of Christ himself, not tossed one way and another and carried along by every wind of doctrine.
Hence it is not about the beginnings of faith that St Paul is speaking, the faith by which they were born, but about the strengthening and perfecting of that faith: I must go through the pain of giving birth to you all over again, until Christ is formed in you. Elsewhere he talks of the same labour in other words: My anxiety for all the churches. When any man has had scruples, I have had scruples with him; when any man is made to fall, I am tortured.
