Augustine of Hippo

(Serm. in Mont. i. 7.) Had He only said, That they may see your good works, He would have seemed to have set up as an end to be sought the praises of men, which the hypocrites desire; but by adding, and glorify your Father, he teaches that we should not seek as an end to please men with our good works, but referring all to the glory of God, therefore seek to please men, that in that God may be glorified.
