I rather dislike this phrase since it comes across as "superior" and patronising but with the increase in secularism and decline in church attendances it has become increasingly marked. In England it manifests itself as an issue when people who do not normally attend church come to a funeral, wedding or baptism. Sometimes they sit at the back and talk amongst themselves. Normally they don't join in the hymns. If they are in the majority, this can be an embarrassment. Our Vicar is quite good about this. She realises that they are not used to church services and manages to explain things in a friendly way without being patronising. Hymns are sometimes replaced by CD playings. I wondered if this was an English thing? English people are liable to be self-conscious and inhibited. I once attended a funeral in Australia where I'm sure the majority of those present were not regular churchgoers, yet they all sung the hymn Immortal Invisible with great gusto. Incidentally, if you attend a football (soccer) game in England you will hear loud and rumbustious chanting. Ironically some of these chants are to hymn tunes.
