The Great Cleric

Info:

A young japanese salaryman is killed by a gunshot and reincarnated by a goddess in an alternate, fantasy-like world as Luciel, a teenager blessed with healing magic. To make sure that this time he lives a long and happy life, Luciel works hard to improve himself. As he rises in the ranks of the clergy, Luciel uses his powers to assist those in need, while helping restore the church’s reputation, tarnished by the greed and corruption of many of its members, making friends and enemies along the way.
