βασιλεία τῶν οὐρανῶν ἐντὸς ὑμῶν ἐστί. περὶ δὲ τὸν ἐντὸς ἄνθρωπον οὐδὲν ἕτερον ἢ θεωρία συνίσταται. θεωρία ἂν εἴη λοιπὸν ἡ βασιλεία τῶν οὐρανῶν. - Basil of Caesarea

We must try to keep the mind in tranquility. For just as the eye which constantly shifts its gaze, now turning to the right or to the left, now incessantly peering up and down, cannot see distinctly what lies before it, but the sight must be fixed firmly on the object in view if one would make his vision of it clear, so too man's mind when distracted by his countless worldly cares cannot focus itself distinctly on the truth.

Who are the greedy? Those who are not satisfied with what suffices for their own needs. Who are the robbers? Those who take for themselves what rightfully belongs to everyone. And you, are you not greedy? Are you not a robber? The things you received in trust as a stewardship, have you not appropriated them for yourself? Is not the person who strips another of clothing called a thief? And those who do not clothe the naked when they have the power to do so, should they not be called the same? The bread you are holding back is for the hungry, the clothes you keep put away are for the naked, the shoes that are rotting away with disuse are for those who have none, the silver you keep buried in the earth is for the needy. You are thus guilty of injustice toward as many as you might have aided, and did not.

You seem to have great possessions! How else can this be, but that you have preferred your own enjoyment to the consolation of the many? For the more you abound in wealth, the more you lack in love.
