"Gloria in Excelsis Deo!"

My wonderful Pastor, who just so happens to be my amazing husband...has been challenging  our church family this year. He minored in Biblical Languages in college (yes, it's true) I am in awe of how sometimes he can just pick up his Hebrew and Greek Bible's and just start reading them which he does to stay fluent so if he ever has a chance to teach it again then he won't be so rusty. Anyway, I do have a point. Do any of you know what "Gloria in Excelsis Deo" means? I will not be posting the answer right away, but will be soon. Take time to research it and when you know the answer...take time to think about it.
