Who now rejoice in my sufferings for (r) you, and fill up (s) that which is behind of the afflictions of Christ in my flesh for his body's sake, which is the church:
(r) For our profit and benefit.
(s) The afflictions of the Church are said to be Christ's afflictions, by reason of that fellowship and knitting together that the body and the head have with one another. And this is not because there is any more need to have the Church redeemed, but because Christ shows his power in the daily weakness of his own, and that for the comfort of the whole body.
