Do you see any difference between dieting to lose weight and practicing bulimia? Between eating a second serving then vomiting it up versus simply not taking a second serving? Both achieve the same end so in your world both are morally equivalent?
Apparently essential moral distinctions are beyond your comprehension because its “not in the bible.”
Except these are not "essential moral distinctions" you are trying to assert. They are commandments your church has decided it can demand every Christian follow - without Biblical basis - and condemns with eternal hell all those who dare to think for themselves in obedience to Christ who see the issue differently. You complained that nobody was engaging with you on the topic of contraception, but look at how you treat those of us who have. You've leveled personal invectives at me three or four times on this thread. If you don't agree with my points, then why can't you just give your own view and agree to disagree? If you show no respect to those who engage in a dialog with you, I think you can figure out why you haven't been able to generate more back and forth. Have any of your opponents told you you are going to hell if you don't believe in the exact same things they do? Have you been told the spirit you follow can't be the Holy Spirit because you don't agree with them on a subject Scripture is mostly silent about? We have ALL that we need from God's holy word to teach us how to live Godly lives and what He expects of us who follow Him. I accept that you have the right to believe what you want on this subject. I've explained my views and why I hold to them. Mutual respect is good standard for how forums such as this should proceed.
And, for your amusement, to answer your quirky example of dieting vs. bulimia and their "moral equivalence" to contraception, I'd say there is NOT a valid moral equivalence. If you are trying to lose weight, you must use up more calories than you take in. Using bulimia or anorexia or any other eating "disorder" is wrong simply because it is harmful to the body to do those things. If you wanted to satisfy your sweet tooth without jeopardizing your diet, for example, you can eat noncaloric or low calorie foods. Your body is tricked into feeling satisfied without adding extra calories and gaining weight or slowing down your weight loss.
If you and your spouse want to satisfy your sexual needs without the risk of adding another baby to your family, you can utilize "methods" that help prevent conception/fertilization. Methods exist that do NOT cause the death of a child. And just like eating too much of the "nonfattening" foods can confound your weight loss goal, so can too much sexual activity, using methods that block fertilization, add statistical risks that the method might fail and a child is conceived. Either way, responsible Christians accept the risk and welcome the child into their lives as a gift from God and part of His plan for their marriage. Other than this, that is about as far as I think you can take this "example" likening dieting to contraception. I've already said I reject abortifacient methods.
