Ha! You must be part of the Eparchy of Passaic. Three years is on the low end. For the last 50 years we were told it wasn't necessary to 'change rites'. Now they want everyone who shows up at the door to BE Byzantine, but don't really assist anyone in doing so. They have no idea what they want- other than your envelopes. Google " smithown" and "parishioners" and read first-hand the ethnic cleansing process that emptied that church over the last two years.
Don't bother changing and keep your envelopes to yourself. The general consensus is that they want all the Latins out now, which will leave a skeleton crew in the pews, allowing them to sell off the properties due to declining membership. Go figure. This is the method of Ruthenian Evangelization, LOL.
