People have strong views about Church music which they are not afraid to express. When Catholics suddenly started singing hymns at Mass in the 1970s, we borrowed some traditional Protestant hymns. We must be careful about the content, but many of them are fine. More suspect music was imported from other sources. A generation of Catholics grew up fond of the catchy tunes they sang as schoolchildren. Yet everything we say and sing in church must accurately reflect what we believe, what God has shown us to be true.
