Egypt was once the centre of the highest spirituality on Earth but then it descended into a concern with magic and power and became the oppressive nation we know of from the time of Moses. Israel was once the focus of God's attention, a chosen nation that was the ground from which the Messiah was born, but then it too descended into materialism, corruption and legalism. Christianity was a religion that gave the believer direct access to the Son of God but it gradually lost power as too many of its leaders succumbed to this world, and now its outer structures remain in place but the fire burns low.
Nothing lasts in this world and that is truer than ever in our day which is a time of increasing destruction. There is no outer spiritual body that will save you if you put your trust in it. The time has come when all aspiring souls must strive for truth within themselves. They can still use the outer forms but they must not allow themselves to be restricted by them. I know there is a verse in the Bible in which Jesus says the gates of Hades will not overcome his church but almost immediately afterwards he calls Peter, Peter the rock on which he will build that church and whom he has just praised fulsomely, Satan! I don't think we can build an entire spiritual edifice on one verse particularly when it can't be certain what Jesus meant by the word 'church'. And given the recent arguments about inner discernment and outer authority we should also note that Jesus commended Peter for knowing he was the Messiah because he had had that revealed to him not by flesh and blood (outer authority) but by his Father in Heaven (inner knowing).
I have to say that some people seem to mistake the lamp for the light. You can have a beautiful lamp, made of gold and adorned with jewels and with finely polished glass so that it allows the light to pass through clearly and without obstruction. But it is still the lamp. What is more, the glass can get dirty unless it is regularly cleaned, even replaced when it gets old. When that happens those who look for light in a pure form may have to look elsewhere. Some light may still pass through discoloured glass but it is less than it was and to pretend otherwise will help no one. Those who look elsewhere may still value the lamp for its beauty and the light it continues to transmit but what they really seek is light and they will look for that wherever it may be.
Why do we come into this world? If it is just to obey an outer authority we could do that better in the higher worlds. But if it is to learn to become a real divine being then we have to reach inside ourselves to find the living God there. The church serves supremely as a bastion of tradition and authority but it is like a mother. The growing child cannot stay clinging to its mother or it will never grow. Naturally, it will always love and respect its mother but if it is to become a mature adult it must start taking responsibility for itself.
Those designated Romantic Christians merely believe that the sabbath was made for man not man for the sabbath. They see the Christian religion as a living thing but living things either grow or start to decay. No one is saying the church should adapt to modernity because that is tantamount to saying it should secularise itself which is more or less what the Church of England has done to its catastrophic loss. But that is changing in a negative sense. There is positive, creative change too that reflects a deeper engagement with spirit (rather than accommodating to the world) and that is all the Romantic Christians are interested in. Speaking as one who may be said to fall into that category, I would say RCs (no pun intended) love and respect the church but their real love is for Christ and they will seek him everywhere.
