I’m not sure the church is ever ok with using birth control for acne or health reasons. First of all, there are MANY times a doctor will seemingly automatically prescribe BC if ANY female issues arise. Often there are other courses of treatment.
Also, you have to remember, the pill is an abortifacient, meaning you could be having abortions while on the pill without even knowing it. The pill is able to break apart conception (conception is a baby).
I go along with the recommendation to read Christopher West’s book. I read it after someone else on one of these forums recommended it. It REALLY is a beautiful book. I didn’t have any real reason to read it other than it sounded interesting yet it really helped renew, strengthen and even in certain instances, change my perspective.
