I know that couples have to plan their family and for that there is natural family planning. The way to plan the family is natural family planning, not contraception. In destroying the power of giving life, through contraception, a husband or wife is doing something to self. This turns the attention to self and so it destroys the gifts of love in him or her. In loving, the husband and wife must turn the attention to each other as happens in natural family planning, and not to self, as happens in contraception. Once that living love is destroyed by contraception, abortion follows very easily.
