John Chrysostom

Note, that speaking of tithes He said, These things ought ye to have done, and not to leave the other undone: for tithes are a kind of alms, and what wrong is it to give alms? Yet said He it not to enforce a legal superstition. But here, discoursing of things clean and unclean, He does not add this, but distinguishes and shews that external purity of necessity follows internal; the outside of the cup and platter signifying the body, the inside the soul.
