The New Liturgical Movement posts an address by Cardinal Arinze to Institut Supérieur de Liturgie which was given on Oct 26, 2006. Here is just one snippet of a well worth reading article.
Many abuses in matters liturgical are based, not on bad will but on ignorance, because they "involve a rejection of those elements whose deeper meaning is not understood and whose antiquity is not recognized" ("Redemptionis Sacramentum," No. 9). Thus some abuses are due to an undue place given to spontaneity, or creativity, or to a wrong idea of freedom, or to the error of horizontalism which places man at the center of a liturgical celebration instead of vertically focusing on Christ and his mysteries.
Darkness is chased away by light, not by verbal condemnation. A higher liturgical institute trains experts in the best and authentic [theological]-liturgical tradition of the Church. It forms them to love the Church and her public worship and to follow the norms and indications given by the magisterium. It also provides appropriate courses for those who will promote ongoing liturgical formation for clerics, consecrated people and the lay faithful.
