Oddly enough, in areas where there is a large Muslim or Hindu community, Schools seem happy enough to meet their spiritual needs, whilst ignoring those of the host community.
I don't find this odd at all. Muslims and Hindus actually have spiritual needs to be met, whilst the majority of those in the host community are completely secular and simply don't care.
Students I teach at University have, in most cases, no knowledge at all of Christianity or of its role in shaping their country. I find it so sad that many young people turn to 'Eastern religions' when they finally acknowledge their spiritual urges - as though Christianity originated in the West! One of the great advantages Orthodoxy has is its ability to draw such young people - if only they can be exposed to it.
I find the same thing. I have spoken to many converts (or "reverts" as they like to be called) to Islam, who claim to have left Christianity. But I have yet to meet a single such convert who had knowledge of even the most basic Christian doctrines, such as the Incarnation or the Most Holy Trinity, etc. The fact of the matter is that such people did not leave Christianity, they simply discovered Islam.
For various reasons Orthodoxy in this country has not has a strong sense of mission, but in these times it needs to acquire it. Although not (yet) Orthodox myself, I have found my life enriched by my encounter with it.
Interestingly enough, it is the ROCOR that has been at the forefront of making Orthodoxy accessible in the UK. What I find refreshing about the ROCOR's approach (as opposed to many other jurisdictions) is that, rather than trying to make itself "relevant" to potential converts by adopting various Western customs that have their origins in Catholicism and Protestantism, it is does not deviate in any way from the Orthodox traditions.
Rather, emphasis is placed on the veneration of English (and other Western) Saints, composing Akathists to them, writing icons of them, etc.; reviving old British places of pilgrimage; and other such things, as well as, of course, adopting the English language for worship.
The result: something that is authentically Orthodox, yet authentically English.
The reason why such a huge amount of British people convert to Islam and other religions is that they are fed up and disillusioned with secular British society. I therefore think the ROCOR's approach (which does not attempt to conform to society) will be the one that will prevail in the long run.
But we have a long way to go; may God help us in getting there.
