Fr Paul Bigmore has written a special book of 50 hymns with more words to appeal to people today.
He told Premier's News Hour why he has created it.
He said: "It's important, it's part of our heritage and culture, but not only that I think we have a sense of Christian duty to pass onto the present and future generations."
He said he was inspired by a conversation with the former Archbishop of Canterbury, Rowan Williams and he wanted to breathe new life into the hymns that he learnt as a child but which are now rarely sung.
Fr Bigmore added: "The Welsh language itself has changed... so there's very little Welsh spoken.
"I think it's time really to use old Welsh tunes, and English tunes also, to revive hymn singing through [the] English language of today."
The vicar, who serves in Ynyshir, in the Rhondda Valley, has named the book Songs Of Praise The Valleys Sing.
The Archbishop of Wales Barry Morgan, commented: "Music and hymnody can help us to express our deepest feelings and desires as few other things can.
"Through both, we can speak to God and God can touch our hearts.
"This is precisely what this book of new hymns to familiar tunes does and Paul Bigmore has put us all in his debt."
