If the clergyman is closeted, and most are, this will not be an easy task. However, this task is not impossible. Oaths; investigations where applicable... are a good start. Check out where the clergyman goes on his time off; whether he preaches against homosexality or is silent about it...Undercover investigations have worked as well. I have no reason to fear that in my life. But some out there do fear being exposed.
You are a Deacon correct?
Tom you attend functions within your diocese , you must have a pretty good idea about most of them. My husband's pastor is flaming . He used to hold a position of some power in the diocese but the shortage of priests forced him to pastor.I believe according to RC beliefs as long as he is celibate there is no problem.
I will add this. It is a terrible image problem for the Catholic church to have swishing Pastors before the public eye.
I have heard non Catholics comment that "they are all gay". We both know that is not true. But in my diocese it sure seems tilted that way .
A strong stand by the church on this issue would be a very good first step
