On June 8, 2002, at the dedication ceremony of Sacre Coeur Church in Luxembourg to the Sacred Heart of Jesus, components of the choir perform a dance around the altar, above. The dance was called "Lord, Thou Are Great and Beautiful."
Below, some minutes later, the same youth surround the three priests who concelebrate the Mass. Second row below, Canon Michel Schmitt blesses the mosaic of the Sacred Heart.
Dances on the altar are being performed all over the world with due approval of the respective religious authorities. One of the many bad consequences of Vatican II.
