I, too, thought being opposed to birth control was a Catholic thing that even most Catholics didn’t really believe. I once heard my mom’s Catholic friend say, “If the the pope wants us to have more than 2 kids he can buy their shoes!”
When discussing having a family my husband and I, in our human arrogance, decided on four. Looking back I am ashamed at how we would dare to tell God how many blessings we were going to allow Him to give us. Thankfully, God was merciful and despite our wrong thinking and choices gave us 6 children. I sometimes wonder who we might have missed out on during the 5 years between # 4 and #5 because we chose our own path.
Our 6th seems like an extra special blessing because we lost one before and one after her.
I know this is a topic that gets people quite hot and so in my real life I keep my strong opinions to myself. But really, if a position cannot be supported by supported by scripture, then believers shouldn’t accept it.
I had four, and if I could do it all again I would never use birth control, and I would home school them all.
Some people say “eight is enough”, I know four isn’t enough.
