"Who is he who cannot warn that no woman may take a potion [an oral contraceptive or an abortifacient] so that she is unable to conceive or condemns in herself the nature which God willed to be fecund? As often as she could have con-ceived or given birth, of that many homicides she will be held guilty, and, unless she undergoes suitable penance, she will be damned by eternal death in hell. If a woman does not wish to have children, let her enter into a religious agreement with her husband; for chastity is the sole sterility of a Christian woman."
