A difficult question and one that must be placed in some form of context to make sense. The question, I imagine, is directed at the situation in the USA. Theorectically and legally there is a clear seperation of church and state there. I say clear 'cos in reality it appears in some ways as any but, e.g. Presidential swearing ins, President Reagan's funeral, etc.
Also the thought of education without God strikes me as an impossibility. Though I firmly agree with the poster who pointed out God is not religion and nor is Orthodoxy. Orthodoxy is the 'the pillar and ground of the truth', 1 Timothy 3,15. Orthodoxy rejects the concept of relativity, partiality or the truth somehow not being found in any one 'church' but rather residing in the sum of all of them. Salvation comes only through Jesus Christ, per Our Lord's own words. So Christianity is not one religion among many, each leading equally validly to God, as some teach.
This may be heard to accept, but nevertheless this is the teaching of our blameless Church.
In a secular society therefore what should we seek. Regrettably perhaps the teaching concerning God and salvation may have to fall on the home, the parish and Sunday schools.
One poster referred to America not being a Christian country. It hurts Greeks but I do not believe there is a single Christian country in the world. Countries which owe their past, their structures and so forth to an earlier Christian time, yes. But Christian now, no.
