Condoms have a notoriously high failure rate. They are the least reliable form of birth control.
They are a pretty poor choice for someone who really wants to avoid pregnancy.
How does that mean that the sex act is not potentially procreative?
Using a condom when a woman is fertile is more potentially procreative than abstaining from sex when she’s fertile.
If God is sovereign, then any sex during a woman’s fertile time is potentially procreative, and I’ve met plenty of people who have had surgery to ensure no more pregnancies, and they ended up with them anyway.
NOTHING is fool proof except not having sex.
What is the purpose of a condom?
