In answer to the question--of course you can. As some have answered--but why would you? I've appreciated reading this thread. As a Christian, I've wondered sometimes why unbelievers sing Christian songs. It was particularly helpful for me to read ddw's remarks. Just one twist to add--Whenever friends who profess unbelief sing gospel, it makes me a little sad. I hope that they will come to a time & place in their lives where they will see what, to me, is the truth in the music. Belief comes from a meeting of what is within the person & his/her understanding of God. I hope that I have never pushed my beliefs on anyone, but, friends, when you sing gospel in my presence, I am praying (with no judgement in my heart) that you will come to know the joy, the peace, & the strength that come from my faith.

best to all,
