So a hypothetical scenario:
A young Catholic man and woman marry in a Catholic Church under presumably valid circumstances. Yet one or both of the spouses have maturity or consent issues that could be grounds for an annulment.
However, if these are indeed grounds for annulment, it means that no marriage ever existed. So would such a couple, if they indeed mature and stay truly committed, be without the sacramental grace of marriage. Or could the marriage validate itself if neither ever attempted to divorce or begin annulment proceedings. Remember, the marriage was presumed valid, so it probably wouldn’t occur to them that they need a new marriage ceremony.
I’m fairly familiar with the basic theology of marriages and annulments :(, so I’m interested in the subtle details regard this or similar situations :o
