What great Godly mean have said against contraception

YEP! OPPOSE CONTRACEPTION...SUPPORT LIFE :)

MARTIN LUTHER
(SIXTEENTH-CENTURY FOUNDER OF LUTHERANISM)
"[T]he exceedingly foul deed of Onan, the basest of wretches . . . is a most disgraceful sin. It is far more atrocious than incest and adultery. We call it unchastity, yes, a sodomitic sin. For Onan goes in to her—that is, he lies with her and copulates—and, when it comes to the point of insemination, spills the semen, lest the woman conceive. Surely at such a time the order of nature established by God in procreation should be followed. Accordingly, it was a most disgraceful crime. . . . Consequently, he deserved to be killed by God. He committed an evil deed. Therefore, God punished him" (Commentary on Genesis).
JOHN CALVIN
(SIXTEENTH-CENTURY FOUNDER OF CALVINISM)
"The voluntary spilling of semen outside of intercourse between man and woman is a monstrous thing. Deliberately to withdraw from coitus in order that semen may fall on the ground is doubly monstrous. For this is to extinguish the hope of the race and to kill before he is born the hoped-for offspring" (Commentary on Genesis).
LUKAS OSIANDER
(SIXTEENTH-CENTURY LUTHERAN)
"[Onan’s contraceptive act] was an abhorrent thing and worse than adultery. Such an evil deed strives against nature, and those who do it will not possess the kingdom of God (1 Cor. 6:9–10). The holier marriage is, the less will those remain unpunished who live in it in a wicked and unfitting way so that, in addition to it, they practice their private acts of villainy" (Commentary on Genesis).
JAMES USSHER
(SEVENTEENTH-CENTURY ANGLICAN BISHOP)
"How doth a man exercise uncleanness in [the sexual] act? Either by himself or with others. How by himself? By the horrible sin of Onan (Gen. 38:9), lustful dreams and nocturnal pollutions . . . arising from excessive eating and unclean cogitations or other sinful means" (On the Seventh Commandment).
SYNOD OF DORT
(SEVENTEENTH-CENTURY CALVINIST COUNCIL)
"[Onan’s contraceptive act] was even as much as if he had, in a manner, pulled forth the fruit out of the mother’s womb and destroyed it" (Dutch Annotations on the Whole Bible, authorized by Dort).
COTTON MATHER
(SEVENTEENTH-CENTURY PURITAN)
"It is time for me to tell you that the crime against which I warn you is that self-pollution, which, from the name of the only person that stands forever stigmatized for it in our Holy Bible, bears the name of ‘onanism’" (The Pure Nazirite).
JOHN WESLEY
(EIGHTEENTH-CENTURY FOUNDER OF METHODISM)
"Onan, though he consented to marry the widow, yet to the great abuse of his own body, of the wife he had married, and the memory of the brother that was gone, refused to raise of seed to his brother. Those sins that dishonor the body and defile it are very displeasing to God and evidences of vile affections. Observe, the thing which he did displeased the Lord—and it is to be feared; thousands, especially of single persons, by this very thing, still displease the Lord and destroy their own souls" (Commentary on Genesis).
