Finding our way and our faith

Schmacey's daughter will receive her First Holy Communion this Sunday.  Being that I'm not Catholic nor have I been confirmed, the whole experience is lost on me.  Instead I'm hung up on if the word "first" should be capitalized.  Schmacey has asked that those around her daughter write letters to her about this accomplishment.  I asked for help on the letter.  I love the idea of her parents reading the letters to her before her confirmation and I totally want to write a letter.  I asked for help and Schmacey said that it didn't matter if I was Methodist or Catholic but just to write a letter. 

The problem is I don't understand it all.
