These two verses, though formally (since God is not directly addressed but referred to in the third person) a wish or ‘prayer-wish’, are really tantamount to a prayer. The structure of the sentence may be indicated as follows: (i) God is named (‘the God of peace’); (ii) an adjectival clause follows (as very often in collects); (iii) the first part of verse 21 expresses the substance of the petition; (iv) the whole is concluded by a doxology. A most perceptive and stimulating commentary on these verses is afforded by Philip Doddridge's paraphrase, ‘Father of peace, and God of love’, to which we shall refer from time to time.
