What is the Church’s position on using condoms for family planning? I don’t see it being problem because it’s not allowing conception to take place.
The only means of “birth control” that the Church allows to be used in family planning is self-control. If a husband and wife has just cause to avoid having children, the husband and wife may use natural family planning (NFP). NFP allows the couple to gauge the woman’s fertile times and avoid relations during those times. What is not, and cannot, be permitted is for a husband and wife to engage in relations while blocking the natural result of children. Any means that accomplishes this end is not morally permissible.
