"The Bible does not, as far as I can tell, give us any proscription or prohibition with reference to contraception."

Not according to John Calvin:

Deliberately avoiding the intercourse, so that the seed drops on the ground, is double horrible. For this means that one quenches the hope of his family, and kills the son, which could be expected, before he is born. This wickedness is now as severely as is possible condemned by the Spirit, through Moses, that Onan, as it were, through a violent and untimely birth, tore away the seed of his brother out the womb, and as cruel as shamefully has thrown on the earth. Moreover he thus has, as much as was in his power, tried to destroy a part of the human race.

Does the thinking of John Calvin have any role in the modern OCP?

Onan's sin was disobedience to God, refusing to follow Jewish law, and in this case, God's commandment -- so that his dead brother would have a family line, was no mere act of coitus interruptus. Jesus came from Tamar -- it was the Plan of Salvation that He would. Onan could have been in that line-- his loss. It equates to Esau giving up his birthright

[Dr. Eckleburg]

John Calvin is not God. He was a fallible human being like the rest of us. I disagree with him on this point.

Christians get to do that.
