Keluarga berencana alami: Perbedaan antara revisi

[[Pantang seksual|Pantang]] berkala dianggap bermoral oleh Gereja untuk menghindari atau menunda [[kehamilan]] karena alasan-alasan yang dapat dibenarkan.<ref>{{en}} "In deciding whether or not to have a child, [spouses] must not be motivated by selfishness or carelessness, but by a prudent, conscious generosity that weighs the possibilities and circumstances, and especially gives priority to the welfare of the unborn child. Therefore, when there is a reason not to procreate, this choice is permissible and may even be necessary. However, there remains the duty of carrying it out with criteria and methods that respect the total truth of the marital act in its unitive and procreative dimension, as wisely regulated by nature itself in its biological rhythms. One can comply with them and use them to advantage, but they cannot be 'violated' by artificial interference."
