Is there a hymn that's called Greensleeves or Green something?

As a child I was always made to attend hymn practise and as much as I hated going, there was this one hymn that really stood out. I wish I could remember a line from the hymn but I can't. All I know is, the word "creed" is in it. It's a very slow and moving hymn. I also seem to think it was called Greensleeves or something like that, I could however be wrong.
