I think you missed the point:

Where does Bill get off telling us anything about what we should or should not do in our Church?

Shall we tell Muslims what they should do?  How about Jews?

How would you feel if I came to your house--and when you told me it is a house rule that I have to take off my shoes before I enter--that I find that offensive and it needs to change? How would you respond? How would Presbyterians respond if I as a Catholic wrote an article telling them what practices they should change?

Why it is always the Catholics that have to change anyway?
