Teacher crossing boundaries?

Many of the teachers at my childrens' school are religious. We know this because it has come up in conversations and through correspondence with them. Somehow it came up in a conversation between my son and his teacher that she attends a certain church. My daughter's teacher always writes "God Bless" at the end of her notes. It is none of my business what their personal beliefs are. However, I feel that there is a a point where a teacher is crossing the line in discussing personal beliefs with students.

Today was the last day of Kindergarten for my daughter. She was very excited to give her teacher a gift card we had bought from Borders. When she got home, she was equally as excited to show me the thank you card she received from her teacher. The thank you card had a Bible verse on the front and on the inside she ended it with her usual "God bless."

This bothered me. I'm trying to decide if it is something that I should be bothered about or if I'm just overreacting. But, it just seems to me that a school teacher should keep things neutral unless she is personally asked about her beliefs.

When confronted with a situation like this, I try to think of how people might react if the tables were turned. Would others be justified in their disapproval if a Muslim teacher had a quote from the Koran on a thank you card? I think people would definitely disapprove, but the real question is whether the teacher is acting as a state official when they write this or if it is being written as a personal note.

I am going to give my daughter's teacher the benefit of the doubt and assume she was writing this as a personal note. However, I am not sure this is something my daughter can really distinguish. To her, her teacher is her teacher...a personal relationship has not been developed. That is, she only sees her teacher at school in a professional environment. So to her, she is getting a religious message from a state official. That's just not OK with me. And, I think other parents would be justified in their disapproval of a note with a verse from the Koran written on it.

I'd like to talk to the teacher about this, but I am trying to decide exactly what I should say. I do not want this to be a confrontational thing. I just want her to know that she offended me and maybe she'll learn to be more careful about her religious expressions to her vulnerable students. I'm going to keep thinking about how to handle this....any suggestions from anyone else who has been in a similar situation would be welcomed :)
