But let us think through this for a moment and consider the adjectives that have been given when it comes to the subject of birth control. Words such as evil, crime, insidious, vicious , and wicked have been applied to this practice by those whom LDS people have been told cannot lead them astray. Yes they do. But this difference of opinion is based more on a lack of biblical evidence rather than abundance. We find no command in Scripture that states that limiting the size of the family is a sin or that such a practice is punishable by damnation.
Christians are free to have as many children as they wish or as few as they wish.
It is up them to prayerfully decide what is best in their given situation. Christians can hold a more dogmatic position than this, but to do so would be without solid biblical support. LDS leaders of the past have spoken on this subject - and spoken quite forcefully I might add.
