Prevention of birth is premature murder, and it makes no difference whether it is a life already born that one snatches away or a life that is coming to birth.
TertullianPrayer cleanses from sin, drives away temptations, stamps out persecutions, comforts the fainthearted, gives new strength to the courageous, brings travellers safely home, calms the waves, confounds robbers, feeds the poor, overrules the rich, lifts up the fallen, supports those who are falling, sustains those who stand firm.
Tertullian[Hermogenes] despises God's law in his painting, maintains repeated marriages [almost certainly a reference to remarrying after divorce or perhaps even widowhood, which Tertullian, who became a Montanist, opposed], alleges the law of God in defense of lust [likely same reference], and yet despises it in respect of his art.
TertullianNow we allow that life begins with conception, because we contend that the soul also begins from conception; life taking its commencement at the same moment and place that the soul does.
TertullianDo you not know that you are Eve? The judgment of God upon this sex lives on in this age; therefore, necessarily the guilt should live on also. You are the gateway of the devil; you are the one who unseals the curse of that tree, and you are the first one to turn your back on the divine law; you are the one who persuaded him whom the devil was not capable of corrupting; you easily destroyed the image of God, Adam. Because of what you deserve, that is, death, even the Son of God had to die.
Tertullian
