I can accept white vestments as a provision for funeral in Asia where it is the traditional colour for mourning (was it ever intended they should be used in the West?), using drums instead of bells, portraying Our Lady as African or Asian or Anglo-Saxon, using, at least outside of the sanctuary, Asian or African modes of reverence. However it wasn't inculturation but exculturation which I thought was interesting. I remember both Cardinal Arinze and Ranjith complaining that many missionaries imposed, almost with imperialistic disregard western modes of informality on Asian and African liturgy. A nod of the head might be acceptable in North London but in Abuja or Columbo bowing or even prostration, walking or crawling backwards might be more cultural suitable.
In the West, I wonder, has the Liturgy, and the Faith generally, been inculturated or exculturated.
Visiting a great and ancient cathedral where perspective, proportion, sculpture, painting point to a particular sacred focus, the altar or the tabernacle something absurd seems to be being said when a priest quite literally turns his back on it all and says Mass on an ill suited johnny-come-lately liturgical carbuncle of an altar.
Are we inculturating or exculturating when we ignore the beauty of the great musical masterpieces and substitute something written a few days ago by a not very talented jobbing musician, whose work has not stood the test of time.
In the West, the very hermeneutic of discontinuity, at least on a cultural level has come back to bite the Church savagely on the backside. So often the Church that produced the great medieval master builders or renaissance painters or baroque musicians is so obviously, not today's Church. The very disregard for the vast riches of Christian culture has been a very grievous blow to both the Church and the West. In many ways the Church itself has contributed to the growth of Secularism by our own disregard and contempt for our heritage.
Pope Benedict's words, "What earlier generations held as sacred, remains sacred and great for us too, and it cannot be all of a sudden entirely forbidden or even considered harmful" are worth applying to not only the Traditional Liturgy but also to Catholic culture generally.
