Clement of Alexandria Stromata Book I "As, then, we have opportunity, let us do good to all, especially to the household of faith."[18] Tertullian Against Marcion Book V and "as we have opportunity, let us do good."[186] Cyprian Treatise VIII On Works and Alms Let us, while there is time, take thought for our security and eternal salvation, according to the admonition of the Apostle Paul, who says: "Therefore, while we have time, let us labour in what is good unto all men, but especially to them that are of the household of faith. But let us not be weary in well-doing, for in its season we shall reap."[62] Cyprian Treatise IX On the Advantage of Patience Moreover, in another place, the same apostle instructs the righteous and the doers of good works, and them who lay up for themselves treasures in heaven with the increase of the divine usury, that they also should be patient; and teaches them, saying, "Therefore, while we have time, let us labour in that which is good unto all men, but especially to them who are of the household of faith. But let us not faint in well-doing, for in its season we shall reap."[31] Constitutions of the Holy Apostles Book VII but so that the saints be preferred.[27]
