This is very distressful and ever mindful of our complete dependence on heaven I am praying my rosary for you, your shepherds and this situation. I wonder...what would Our Lady do in your position.
I also attend Mass in Spokane, and am familiar with the shepherd there, I have no doubt he probably spoke to this person who was wearing pants in private.
I must have missed the event Emerentiana is speaking about since I can't imagine who it could be.
I've seen a few women doing yard work in the grotto outside wearing pants, and once in awhile someone painting outside, a project wearing pants, but haven't noticed anyone wearing them inside the church, except for visitors.
We get many visitors, especially on the weekend, I like to talk to them and encourage them to come back. One time we had this guy, who was full of tattoos come and visit the chapel on a Saturday while I was cleaning. He started asking me questions about the Christmas Eve Mass schedule so I saw father walking by and put the two together.
We have this one couple who were not raised Catholic, but they are members of our Church now, the man told me his story. It seems he had this re-occuring dream that he walked into a church.
Well this one day he and his wife saw the Mount in the distance and wondered what it was, because it looks like a castle in the sky from a distance. They came up there and wandered into the gift shop, then were invited into the chapel, and when they walked in, he almost passed out because he said, this is exactly the picture in his dream. Needless to say, they are both Catholic today.
Sorry I got off topic.
