Of Prayer, by John Calvin, tr. Henry Beveridge , at sacred-texts.com
The instruction given us, however, is not that every individual in particular is to call him Father, but rather that we are all in common to call him Our Father. By this we are reminded how strong the feeling of brotherly love between us ought to be, since we are all alike, by the same mercy and free kindness, the children of such a Father. For if He from whom we all obtain whatever is good is our common Father (Matthew 23:9), everything which has been distributed to us we should be prepared to communicate to each other, as far as occasion demands. But if we are thus desirous as we ought, to stretch out our hands and give assistance to each other, there is nothing by which we can more benefit our brethren than by committing them to the care and protection of the best of parents, since if He is propitious and favourable nothing more can be desired. And, indeed, we owe this also to our Father. For as he who truly and from the heart loves the father of a family, extends the same love and good-will to all his household, so the zeal and affection which we feel for our heavenly Parent it becomes us to extend towards his people, his family, and, in fine, his heritage, which he has honoured so highly as to give them the appellation of the " fulness" of his only begotten Son (Ephesians 1:23). Let the Christian, then, so regulate his prayers as to make them common, and embrace all who are his brethren in Christ; not only those whom at present he sees and knows to be such, but all men who are alive upon the earth. What God has determined with regard to them is beyond our knowledge, but to wish and hope the best concerning them is both pious and humane. Still it becomes us to regard with special affection those who are of the household of faith, and whom the Apostle has in express terms recommended to our care in everything (Galatians 6:10). In short, all our prayers ought to bear reference to that community which our Lord has established in his kingdom and family.
