I knew this minister (who was formerly Episcopalian) who was part of a non-denominational charismatic cyber-church and I think he explained it best. You make Jesus Lord and he gradually goes through your life and helps you find the parts that need healing, but he does this as a friend not a judge. I've heard similar messages preached at the Episcopal church I am at in RL.
As I'm sure you're aware we tend to see Christ as the Great Physician. I don't think you'll find the idea of Christ judging us for not being perfect (as opposed to willing us and helping us to be perfect) to be common amongst the Orthodox. It's certainly not what I meant when I noted the almost complete absence of striving to be perfect (and I'm talking about us doing our best to follow Christ's example, not about being forced to by others) in my experience of 20+ years worshipping in Anglican churches.
FWIW, I do often strive to be perfect ... probably too much at times to the point it causes me mental issues. Different people need to hear different messages. That's why its about having a relationship with Jesus through the Spirit, not a bunch of rules to follow, which is legalism.
I don't agree that people need to hear different messages. 'Go and sin no more' and 'be perfect as your Father in heaven is perfect' are quite general and applicable to everyone. Everyone does need to be given different pastoral advice. Everyone does need to be treated as an individual. Everyone needs different help on their journey but that doesn't alter the destination. Everyone cannot strive to be perfect in the same degree or at the same rate, but everyone should be striving as they are able. That's very far from legalism indeed, and its precisely this individual pastoral care that in my experience Orthodox priests excel at and Anglicans do precious little of.
If I went to my priest (or any of the others I know) and confessed some difficulty or failing on my journey I would get advice tailored to my needs and experience tells me it would likely help but if it did not I would return and we would try to find something else that did. Never would I be told, though, that it didn't matter anyway, that I couldn't be perfect so why bother, that I'm only human and we all sin so Christ was happy and approving of me 'just as I am'. All things I've heard from Anglicans both lay and clergy.
One of the greatest failings I see (in my experience) in Anglicanism is that rather than being helped to 'go and sin no more' people are told 'never mind your sins just come as you are'. I know the people who do this think that they are being more loving, but they really aren't. True love does not leave people wallowing in their filth for fear that a helping hand might be wrongly perceived as harsh.
