Do you think that, because of sin, the usual minister of the Sacrament of Confirmation (your bishop or his representative) can no longer do so validly?
Do you think the "Gates of Hell" have in fact prevailed, and thus Christ's mission has failed?
Or do you no longer wish to receive the Holy Spirit because of faults and sinful mistakes of some in the household of the Faith?
What is the nature of your difficulty?
I do have questions of this nature. Not only because of sin but also, possibly, sloppy or incorrect liturgical procedures.
Do you think the "Gates of Hell" have in fact prevailed, and thus Christ's mission has failed?
No. I think vestiges of the True Church remain. I'm positive they do.
Or do you no longer wish to receive the Holy Spirit because of faults and sinful mistakes of some in the household of the Faith?
No, nothing to do with the situation.
Thanks for the thought you put into the questions! I may resolve my on-going stalemate on this by traveling to an FSSP parish, where things are still as they should be, as far as I can tell.
I should qualify the part of that having to do with “faults and sinful mistakes”.
No, those fallen from Grace do not dissuade me from receiving the Sacrament of Confirmation in my normal parish/diocese.
I think, however, that God allowed those transgressions to occur as a consequence of errors the Church made in the modern era.
This tarnishes the Church but does not destroy it.
