That's what I've always said.
St. John of the Cross writes: "It is also vain to desire children, as some do in upsetting the whole world with their longing for them. For they do not know whether their children will be good and serve God, or whether the expected happiness will instead be sorrow, or the rest and comfort, trial and grief, or the honor, dishonor. And because of the children they might, as many do, offend God more. Christ says of these people, that they circle the earth and the sea in order to enrich their children, and they make them children of perdition twofold more than they themselves are. [Mt. 23:15] - Ascent, Bk. III, Ch. 17:4
"Desire not a brood of worthless children, nor rejoice in wicked offspring. Many though they be, exult not in them if they have not the fear of the Lord. Count not on their length of life, have no hope in their future. For one can be better than a thousand; rather die childless than have godless children." - Sirach 16: 1-3
"Better is childlessness with virtue..." - Wisdom 4:1
