We met with a priest.  We were asked questions.  We probably signed what we should have signed.  It was a long time ago.  It was never identified as a "prenuptial enquiry" to us but rather as an obligation to meet with the priest before we could be married in the Church.  If that priest did not do his duty, his lapse would not invalidate our sacrament.  We were ready to comply with the requirements of the Church.  It has NO bearing on being able to recognize apostasy in other matters.
