Is that the best you can do, because the "Church" tells you so? The "Church" at one time told me that I had to fast from the night before prior to receiving communion, then they said only one hour before, now it's you can if you want to. The "Church" used to tell me I had to wear a veil over my head attending Mass - even if it was only a hanky or kleenex - now you don't have to. The "Church" used to tell me that only good, obedient Roman Catholics could ever go to heaven, now it's really anyone who just tries to do their best, regardless of whether they even believe in God or not - except those nasty "Protestants" - they are hell-bound for sure. There is no consistency there to believe that is why I base my faith on what God's holy word says.
The Eucharistic fast is set at one hour. Yes, those things change from time to time, and will probably change again, but no one who has a clue about the Catholic Church bases his faith on these matters. The matters of faith are the virgin birth, death and resurrection of Christ, His teachings, the history of the Church -- all those things without which there would be no Protestantism either. The difference is that we believe wholly and you believe selectively. We also believe directly and you believe through the filter of your pastor. But we both believe the Church. There is simply no ohter source of knowledge about the salvation Christ offered you.
