It falls when you die and fine out your faith was in the wrong thing. It falls when Jesus returns and reveals it to have been false.
By this do you must mean that all Christians who died prior to the early 16th century, as well as Catholics and Lutherans since then (and a great many Calvinists and Methodists) are burning in Hell. Do you actually believe that from the time of Apostle's deaths onward that it was over 15 centuries before another soul entered Heaven?
And what of all of those who (and presumably this will include all of us) who die prior to Christ's Return?
What if you, Biblewonk, are the one who is wrong? Will you be given the opportunity to repent?
My faith is in Christ. Christ is present in the sacraments. No other denomination claims that the Trinity cooperates with the Church as the RCC does - spiritually AND physically.
Thus, by remaining faithful to the Catholic Church, I am remaining faithful to Christ.
You, on the other hand, can only remain faithful to your intellect and literacy.
In the Catholic Church, one does not have to hear, see, taste, touch anything or speak any words to be "saved". By receiving just a speck of the Holy Eucharist or a drop of the consecrated wine, Christ is most alive within the recipient.
Terri Schiavo did not have the ability to say, "I accept Christ as my savior." She received the Eucharist intravenously and was absolved of all her sins in spite of her incapacity.
House of cards? I think not.
