The other kills God’s intent to make a baby. Just as bad.
It also allows for the attitude that pregnancy is a mistake. And though the circumstances can be outright disastrous it would be wrong to say a baby is a mistake.(A contraceptive mentality).
It is not that much of a leap to go from a contraceptive mentality to abortion may be alright in some cases. After all often the very circumstances of a woman or family’s life that are cited as reasons to use artificial birth control are used as reasons for abortion.
To me the acceptance of artificial birth control and abortion(even if for limited reasons) are linked. Also the acceptance that the unitive and procreative aspects of sex can be artificially separated has made it much easier for society to approve gay relationships including pseudo marriage.
Respectfully disagree — a married couple where the man uses a condom is not a, “sin”. But I come from a Protestant tradition.
