Nevertheless, it is possible, and it depends on the whims of the local ordinary. So it is necessary to understand the situation in Belgium in order to understand the NSA Chapel controversy. There is an English-language parish nearby, where most of the US Catholics officially assigned to Brussels attend Mass on Sundays and Holy Days. They have all the features of modern Catholicism, going way beyond the directives of the Second Vatican Council. Not only is there is no Latin, there is no kneeling, there is not normally any First Confession prior to First Communion, and there are girls all over the altar on Sundays.
Nobody can remember when was the last time a young man left the parish to go to a seminary.
My family normally attends Mass in a church in the French area, and my children are in the school downtown. Vocations are common in these traditional Catholic communities. Over the last year our parish choir directress and my oldest son's teacher have both departed for convents. The situation in Belgium, therefore, is such that there should be no controversy over the introduction of the old Mass into a US Military chapel. He informed us that this Mass was not possible since Cardinal Danneels of the Archdiocese of Mechelen-Brussels did not approve the request.
