This does not mean that the Christian must make children in series. I rebuked a woman some months ago in a parish who was pregnant eight times, with seven C-sections (cesareans). “But do you want to leave seven orphans? That is to tempt God! (Paul VI) speaks of responsible parenthood.
Therefore, to give you an answer, they key word is the one the Church always uses all the time and even I use it: it is responsible parenthood. how do we do this? With dialogue. Each person with his pastor seeks how to do that responsible parenthood .
That example i mentioned shortly before about that woman who was expecting her eighth (child) and already had seven who were born with caesareans. That is an irresponsibility (That woman might say) 'no but I trust in god' But God gives you methods to be responsible. Some think that, excuse me if i use that word, that in order to be good Catholics we have to be like rabbits. No. Responsible parenthood! This is clear and that is why in the church there are marriage groups, there are experts in this matter, there are pastors, one can seek and i know so many, many ways out that are licit and that have helped this. you did well to ask me this.
