Gregory the Great — on 1John 3:11 (Morals on the Book of Job, Book 21, Section 29)

“But on the other hand, others are not forward to support their needy brethren with things; but only to cherish them with soft words. Which persons the holy preaching of James strongly rebukes, saying, If a brother or sister be naked, and destitute of daily food, and one of you say unto them, Depart in peace, be ye warmed and filled: notwithstanding ye give them not those things which are needful to the body: what shall it profit you? Which persons the Apostle also admonishes, saying, My little children, Let us not love in word, neither in tongue: but in deed and in truth. For our loving affection must always be shewn forth at once by respectfulness of speech, and by the service of almsgiving.”
