Doxology...

When I was growing up, my family attended church services every Sunday.  Part of every service was the doxology which was repeated so many times in all the years I went to church that I have always remembered it although at the time it was never explained to me - my parents never discussed the weekly service they were so adamant about attending.  The doxology just seemed like something that was dutifully repeated by church goers every Sunday - right after the collection plate got passed around.  For me it meant the long boring sermon was coming up soon. 

Praise God, from whom all blessings flow,
Praise Him all Creatures here below,
Praise Him above ye Heavenly Host,
Praise Father, Son, and Holy Ghost. 

Recently it came to mind and I did a little research.
