re: "liturgical dance"
On January 8,1982, in answer to a question regarding liturgical dance, the Sacred Congregation for the Sacraments and Divine Worship referred to an article in its official journal, Notitiae, XI, 1975, pp. 202-205
"In the Byzantine Liturgy, there is a very simple dance [procession] on the occasion of a wedding, when the crowned newly married couple goes around the lecturn with the celebrant...However, the same criterion and approach cannot be applied to western culture. Here, the dance is connected with love, with amusement, with profanity, to rouse the senses, such a dance, usually, is not pure. Hence it is not possible to introduce something of that sort in the liturgical celebrations: it would mean to bring into the liturgy one of the most desacralized and desacralizing elements; and this would be seen as introducing an atmosphere of profanity, which would easily suggest to those present worldly places and profane situations.
Nor is it acceptable to introduce into the liturgy the so-called artistic ballet because it would reduce the liturgy to mere entertainment...If it were the case that the suggestion of liturgical dance in the West should be accepted, there would arise the obligation that the dances should take
place outside the Liturgy at a time and place where they are not considered liturgical celebrations. And from such dance priests should always be excluded."
