"The argument for conjugal contraception could be summarized as follows. The marriage act has two functions: a biological or procreative function, and a [spiritual]]-unitive function. However, while it is only potentially a procreative act, it is actually and in itself a love act: it truly expresses conjugal love and unites husband and wife. Now, while contraception frustrates the biological or procreative potential of the marital act, it fully respects its spiritual and unitive function; in fact it facilitates it by removing tensions or fears capable of impairing the expression of love in married intercourse. In other words - this position claims - while contraception nullifies the procreative aspect of marital intercourse, it leaves its unitive aspect intact."
