But let us speak that which is good, to the edification of faith. That is, to speak only what will help to build up our neighbor in virtue; nothing more than that.
For not only are spiritual riches and heavenly gifts received from God, but earthly and material possessions also proceed from His bounty, that He may be justified in requiring an account of those things which He has not so much put in our possession, as committed to our stewardship. God’s gifts, therefore, we must use properly and wisely, lest the material for good work should become an occasion for sin.
Just as breathing is necessary for life, and just as food is necessary for the sustenance of the body, so is frequent Communion necessary for the life of the soul and for the sustenance of its substance, or rather it is incomparably more necessary.
A person lighting a fire first has a small piece of tinder. This represents the word of the brother who has upset him. This little fire is very feeble. What significance has the word of your brother? If you put up with it you blow out the small fire, but if you begin to think to yourself, 'Why did he say that to me? I myself can answer him. If he did not want to hurt me, he wouldn't have said that and believe me, I can upset him too.' In this case, you add small pieces of wood to the fire and some other fuel like the person that lights a fire and you produce smoke which is agitation. Agitation is the movement and coming together of thoughts which stimulate the heart and make it audacious. Audacity is the taking of retribution against the person that has upset you, and this becomes insolence as Abba Mark said, 'Evil accepted in thought makes the heart audacious, but when this is revoked through prayer and hope, it makes it contrite.'
The more a man's tongue flees verbosity, the more his intellect is illumined so as to be able to discern deep thoughts; for the rational intellect is befuddled by verbosity.
When you are generous to another person, you are not bestowing a gift, but repaying a debt. Everything you possess materially comes from God, who created all things. And every spiritual and moral virtue you possess is through divine grace. Thus you owe everything to God. More than that, God has given you his Son, to show you how to live: how to use your material possessions, and how to grow in moral and spiritual virtue. We may say that your material and spiritual possession cost God nothing; God created the universe in order to express His glory. But the gift of his Son was supremely costly, because His Son suffered and died for our sakes. The agony of Christ on the cross is the measure of how much God loves us. For this reason we should take none of our gifts-- material or spiritual --for granted; day by day we should give thanks to God for what He has bestowed on us. Once this spirit of gratitude infuses us, we shall see generosity for what it is. When we help someone in need, we shall be saved from any temptation to take pride in our actions. On the contrary, we will regard our act as no more than a small token of appreciation for all that we have received - or, more precisely, the repayment of a tiny fraction of God's blessings.
When the door of steam baths is continually left open, the heat inside rapidly escapes through it; likewise the soul in its desire to say many things, dissipates the remembrance of God through the door of speech, even though everything it says may be good. Ideas of value always shun verbosity, being foreign to confusion and fantasy. Timely silence, then, is precious, for it is nothing less than the mother of the wisest thoughts.
If Moses, who was a god to Pharaoh, was shut out from the Land of Promise because of one word, how much more will not the evil speech of our tongue, by which we offend and hurt both God and man, shut us out from heaven?
If Christ is in you through the frequent communion of the Holy Sacrament, then be yourself wholly like unto Christ: meek, humble, long-suffering, full of love, without attachment to earthly things, meditating upon heavenly ones, obedient, reasonable. Have His spirit unfailingly within you.
A single word made the thief pure and holy, despite all his previous crimes, and brought him into paradise (cf. Luke 23:42-43). A single ill-advised word prevented Moses from entering the promised land (cf. Num. 20:12). We should not suppose, then, that garrulity is only a minor disease. Lovers of slander and gossip shut themselves out of the kingdom of heaven.
