Dancing is a natural expression of human nature. The supernatural revelation of God as found in the Holy Scriptures builds on nature while going above and beyond it. 'Worship' is a general term that can cover a lot of territory. In general, there are passages in Scripture (such as David "dancing" before the Ark of the Covenant) which show this as being an authentic possibility in worshiping God. It takes into account and builds on the existing culture of the people, for example. It's kinda God's style in His dialogue with us through the centuries leading to the climax of the Incarnation. The Divine Liturgy is a specific type of public worship primarily performed by God on our behalf, and secondarily received by us and given back to Him.
The Holy Scriptures were not written with the view in mind to give detailed instructions, as if it were a handbook, concerning specifics such as this. The Scriptures do give authority to God's Divinely instituted Church (the pillar of Truth) under the guidance and protection of the Holy Spirit to fill in these details. Hence Sacred Tradition.
The question that this article raises is: Where, when, why and how can dancing be incorporated into the Church's worship to maximize the Glory of God, using the entire being of Her members. I don't see how that can be accomplished in our cultural situation in the Holy Sacrifice of the Mass proper.
