If you send an e-mail to the priest, I would address it to Father Leckie.
When I am speaking with a priest, I often just call him Father, but if I send him an e-mail I always say, “Hello Father X”.
Being a Catholic parish, there is not going to be the variation in belief that you find when “shopping” for a Protestant church.
Going to Mass and attending events would be the best way to see if the parish is a match for you and your family. The bulletin will be a good help.
You might call the secretary and ask for a list of parish organizations. She may have something to mail or e-mail you. She might be the best one to give you a quick over view of the parish. (Sometimes the secretary belongs to another parish near her own home.)
Looking at our parish bulletin, there are several groups that you will not see listed in the bulletin. One is a group that helps weekly at the homeless shelter - making food to bring and serve the residents. There is another group that makes and serves dinner to the men in our diocese who live at the Discernment House before going to the seminary. There are a lot of people involved in a variety of ways with pro-life works in our city, but you will see very little in the bulletin.
I think the best way is to attend Mass and to attend parish events and begin to volunteer in the different programs. Some parishes appear wonderful on paper. Some may appear very lacking on paper. Participation will tell you how the people work together.
You will find in any parish - people who work hard to serve others, people who are very spiritual, people who have a lot of time to give to the parish and those who have less time, people who know a lot about the faith and people who know very little.
You can register as a parishioner at one parish and still check out the other one. You most likely can join activities at both places - but be sure to register at one. If you later decide the other parish is best for you, just register at that parish and let the first parish know you are becoming a member of the other parish. You are welcome to attend Mass at both parishes, but it often feels best to have one that you normally attend Mass.
Enjoy the time of learning about the faith and the parishes.
