Why Hillsong at an RC church,  theology issues, and pop song/country twang style and then there is the copyright issue, no? You are correct that it sounds like substitutionary atonement dogma, which I thought you RC rejected. We don't even sing their stuff in many mainline denominations. To be perfectly candid I was surprised to read RC used it even if "Jesus is my best buddy, don't confuse me with dogma and liturgy" sells big in dumbed down Murrica these days.. Is it used for a young person's mass?
