St. John Cassian
Examples of avarice are...condemned in Holy Scripture. Gehazi wanted to acquire property which he did not previously possess, and therefore never received the prophetic grace which his teacher had wished to leave him in place of an inheritance. Because of the prophet’s curse he inherited incurable leprosy instead of a blessing (cf. 2 Kings 5:27). And Judas, who wished to acquire money which he had previously abandoned to follow Christ, not only lapsed so far as to betray the Master and loose his place in the circle of the Apostles; he also put an end to his life in the flesh through a violent death (cf. Matt. 27:5). Thirdly, Ananias and Sapphira were condemned to death by the apostle’s word when they kept back something of what they had acquired (cf. Acts 5:1-10). Again, in Deuteronomy Moses is indirectly exhorting those who promise to renounce the world, and who then retain their earthly possessions because of fear that comes from lack of faith, when he says: ‘What man is there that is fearful and faint-hearted? He shall not go out to do battle; let him return to his house, lest his brethren’s heart faint as well as his heart’ (cf. Deut. 20:8). Could anything be more clearer or certain than this testimony? Should not we who have left the world learn from these examples to renounce it completely and in this state go forth to do battle? We should not turn others from the perfection taught in the Gospels and make them cowardly because of our own hesitant and feeble start.
Some, impelled by their own deceit and avarice, distort the meaning of the scriptural statement, ‘It is more blessed to give than receive’ (Acts 20:35). They do the same with the Lord’s words when He says, ‘If you want to be perfect, go and sell all you have and give to the poor, and you will have treasure in heaven, and follow Me’ (Matt. 19:21). They judge that it is more blessed to have control over one’s personal wealth, and to give from this to those in need, than to possess nothing at all. They should know, however, that they have not yet renounced the world or achieved monastic perfection so long as they are ashamed to accept for Christ’s sake the poverty of the Apostle and to provide for themselves and the needy through the work of their hands (cf. Acts 20:34); for only in this way will they fulfill the monastic profession and be glorified with the Apostle. Having distributed their former wealth, let them fight the good fight with Paul ‘in hunger and thirst . . . in cold and nakedness’ (2 Cor. 11:27). Had the Apostle thought that the possession of one’s former wealth was more necessary for perfection, he would not have despised his former status a Roman citizen (cf. Acts 22:25). ...the apostle’s considered it more blessed to live off...the offerings of the Gentiles.
