I think this list is very good, with one caveat.
You’ve got to get your house in order. Once you get people through the door, it has to be a place where they want to stay. They have to find Christ in the parish. They aren’t coming for the programs! They might come and be attracted to the liturgy, but if your parish is currently a rather toxic place to be, as you have stated, any visitors that you could bring in are going to be temporary, even if they stay for a while. A person needs to be extraordinaril committed to stay through such a phase. I’ve seen it happen in my own parish and it is painful to watch.
I’ll pray for your parish. Our parishes out west are a precious resource, so few and far between. Hopefully, it will give you some consolation that Bishop Gerald has stated his committment to not closing parishes.
