One thing I've noticed that is lacking in Protestant Christianity, especially evangelicalism, is a thoroughgoing vocational ecclesiology. I mean that there is little willingness to consider any spiritual path outside the mainstream, which is very egalitarian. Everyone can do every job or take on any role, and while there is an understanding of "calling", ie, "I've been called to do ....", that understanding does not extend beyond a very short list of possibilities. That's bad enough, but even within "normal" callings, there is still a social prohibition against specific practices. Take this article from Youthspecialties.com. This guy is describing practices, which historically, are perfectly normal and were widely accepted within the church. I think there is probably some degree of danger in undertaking these exercises without a more experienced guide - one of the key issues in monasticism, from what I understand. But more to the point, he will always be regarded as weird and possibly even mildly disturbed by the evangelical church.
Here are the general categories of exclusions, as I see them...
Exclusion #1 - Monasticism: (leaving aside for a moment that Protestantism has no monastic movement), but in a more general sense. The only people who can legitimately remain unmarried are gay people - and in many churches they are expected to be "cured" and get on with a wife and family already. There is effectively no room for a person to remain single for their entire life and marriage is viewed as the sole ideal for our lives. Perhaps if your spouse dies, you may remain unmarried after that, but that's still a little fishy to some.
Exclusion #2 - Mysticism: Contemplative prayer, fasting, Christian meditation, basically anything that results in an "altered state" no matter how holy. I think we've married ourselves to modernism so thoroughly that we've learned to distrust anything that cannot be rationally explained, which necessarily includes many spiritual things.
Exclusion #3 - Anything that smells like popery: No incense, no candles (except at Christmas), no liturgy, no memorized prayers, no prayer ropes, no sacramental understanding of anything and heaven help us should we actually show respect to Mary or any other saint!
No, numbers 2 and 3 are understandable to me in that I can see how our intense dance with modernism has made us too heady at the expense of being hearty and how the anti-Catholic swing started at the Reformation would lead to the rejection of Catholic trappings. I guess the latter would apply to #1 to some degree, but I guess I don't see why else we would have abandoned monasticism or at least rejected the possibility that some might be called to a life of singular devotion. If anyone has any thoughts, I'd love to hear them.
