No, I believe he turned that over to the Church.
Nah, at the end of Skin Game Michael asks him if he ever considered turning the artifacts over to the church, and Harry's response is "All things considered? Nope", I looked back and apparently he's got them in the deep tunnels of demonsreach.
As to whether or not that's how it's
meant to be used, I dunno. But I'd personally think God would smile upon a person using one of His artifacts to heal someone they love.
