Tertullian

“ Identity of nature abroad as at home, identity of custom in the presence of men as of the Lord, consists in identity of liberty. To what purpose, then, do they thrust their glory out of sight abroad, but expose it in the church? I demand a reason. Is it to please the brethren, or God Himself? If God Himself, He is as capable of beholding whatever is done in secret, as He is just to remunerate what is done for His sole honour. ”

“ It follows, therefore, that what cannot appear to be done for God’s sake (because God wills not that it be done in such a way) is done for the sake of men,—a thing, of course, primarily unlawful, as betraying a lust of glory. For glory is a thing unlawful to those whose probation consists in humiliation of every kind. ”

“ But if we are prohibited from letting “our left hand know” when we bestow the gift of a single halfpenny, or any eleemosynary bounty whatever, how deep should be the darkness in which we ought to enshroud ourselves when we are offering God so great an oblation of our very body and our very spirit—when we are consecrating to Him our very nature! ”
