Adoremus suggests "Dance" is out...

-- "[I]t is strictly to be considered an abuse to introduce into the celebration of Holy Mass elements that are contrary to the prescriptions of the liturgical books and taken from the rites of other religions". (RS 79)

This admonition would apparently prohibit practices such as ritual dances or ceremonies of non-Christian or neo-pagan religions, in accordance with the 1994 Instruction, Varietates Legitimae, on the subject of legitimate "inculturation".

Please, Lord, let it be so!
