(*) here, in good faith I determine that the Church is not legitimately or correctly governed and, therefore, the decision to withhold jurisdiction from the SSPX is not licit. But this generates another doubt... can a faithful usurp the decision/ruling that should rest ptoper only with an Ecclesiastical court? Is it not pride to substitute oneself because one's opinions contradict that of the church? Sorry for this never ending chain of questoins...
Lay people have a duty to make practical judgments on those matters which affect our daily lives. As parents, we are obliged to pass on the Faith to our children. As Catholics, we have an obligation to attend Mass. We must judge how to best do these things in our personal circuмstances. The Church has authority to make general rulings, but we have the authority to apply them to our own lives.
We are in a time of confusion and chaos. Many people faces situations in which following official rulings seems wrong for various good reasons. For example, a person might need to choose between attending a Mass that endangers his faith or one that lacks "official" approval. Such a person is not usurping authority or acting from pride. He is forced by circuмstances to make the decision.
How long did you wait and what did you do inbetween? No Eucharist? No Confession? Only Mass?
During the years before I concluded that I could rightly participate in Sacraments offered by the SSPX, I went through a slow process. First I went to both Novus Ordo and "Indult" Masses. Then I reached a point where my husband basically forbade me to attend Novus Ordo Masses because I would become so upset by them. I attended both SSPX and "indult" Masses but only received Sacraments from "indult". Eventually I decided that it would be right to receive Sacraments from the SSPX. (Technicially, after Summorum Pontificuм in 2007 these were not indult Masses, but they were similar enough that this is a reasonable way to refer to them.)
Sorry it took so long to get back to you. I was babysitting grandchildren this week and it took up the time and energy that I might otherwise have spend on forums.
