"Our sacrifice of praise" vs. "Our hymn of greatful praise"

The last line of the chorus in “For the Beauty of the Earth” puzzled me growing up as an Anglican.
When the CBW III changed the traditional lyrics it made me think of what I was singing. (I was the only one in church singing the traditional words – I knew it off by heart.)
Does anyone know what was really meant in the original? (By “original” I mean the traditional version I knew.)
As a Roman Catholic these words (“Our sacrifice of praise”) make perfect sense in that we’re celebrating the Sacrifice of the Mass. Could that have been the composer’s intent or was it composed by a protestant?

I’m feeling lazy today … maybe someone knows without me doing the work. :wink:
