First: ( a plus) let me say you are correct in seeing this as a pivotal issue. Many prelates and laity do not see what all the fuss is about!
Second: (a minus) you are eradicating a practice which tangibly unites us with the Tradition of our grandfathers and our great grandmothers. As Catholics, should we not only be one with Catholics across the world, but also with Catholics across generations and times?
Third: (a minus) In our lighthearted North American culture it is hard to imagine Catholics getting belligerent over a matter of Faith, but you have now backed many good people into a corner. They must either obey you or obey their consciences. Maybe you remember those old Tareyton cigarrette commercials?
I am including it to illustrate how little people can sometimes be very stubborn!
please reconsider your course of action.
