St. John Chrysostom, The Orthodox New Testament: Acts, Epistles, and Revelation, Vol. 2, Commentary on 1 Timothy 5:8, p. 360.
1 Timothy 5:8: "But if one provide not for one's own, and most of all for those of one's own house, such a one hath denied the faith and is worse than an unbeliever."
The provision of which the blessed Paul speaks is universal and relates to the soul as well as the body, since both are to be provided for ... Isaiah says, 'Thou shalt not disregard the relations of thine own seed' [Is. 58:7]. If a man deserts those who are united by ties of kindred and affinity, how shall he be affectionate towards others? Will it not have the appearance of vainglory, when benefiting others he slights his own relations, and does not provide for them? ... What is meant is that the law of God and of nature is violated by him who provides not for his own family. But how has such a one denied the faith? Even as it is said, 'They confess to know God, but in works deny Him' [cf. Tit. 1:16] ... It was the design of God, in uniting us by the ties of kindred, to afford us many opportunities of doing good to one another. When therefore thou neglectest a duty which infidels perform, hast thou not denied the faith? For it is not faith merely to profess belief, but to do works worthy of faith ... For since he had spoken of self-indulgence, he says that it is not for this only, but a woman is punished if she is luxurious, because her luxury compels her to neglect her household. This he says with reason; for she that liveth to the belly, perisheth hereby also, as having denied the faith. For how is she worse than an infidel? Because it is not the same thing to neglect our kindred, as to neglect a stranger ...
St. Moses the Black
You abandoned the Egypt of the passions, O Father, ascending the mount of the virtues with fervent faith, taking the Cross of Christ upon your shoulders; and being glorified in godly works, you proved to be a model for monastics, O summit of the fathers. Pray unceasingly with them that our souls may find mercy!
Kontakion, Tone 3
Your mind was filled with a holy inspiration from God, turning you from the lust and pleasures of the flesh, bringing you to the height of the city of God! O Holy Father Moses, intercede with Christ God that He may grant us great mercy!
