Jerome on Christian views on birth control

“You may see a number of women who are widows before they are wives. Others, indeed, will drink sterility [oral contraceptives] and murder a man not yet born, [and some commit abortion].”

“"But I wonder why he [the heretic Jovinianus] set Judah and Tamar before us for an example, unless perchance even harlots give him pleasure; or Onan, who was slain because he grudged his brother seed. Does he imagine that we approve of any sexual intercourse except for the procreation of children?”
