Loving oneself is controversial in Christianity. It is usually condemned in any form. As one of my friends and I have discussed several times, many traditions in Christianity seek denial of various loves and desires rather than embracing our deep-seated motivations. That's one of the reasons we like a lot of John Eldredge's work.
Anyway, this is a very interesting post about self-love based on Church Father extraordinaire Bernard of Clairvoux. I like the framing of "The love of self for God's sake" as the highest degree of love, even above "The love of God for God's sake." It really does take a particular level of maturity (psychologically and spirituality) to appreciate oneself, not to compensate for narcissistic injuries, but because we are truly filled with God's love for everyone, including ourselves.
I can definitely say I'm not there. I don't always love myself, and when I do, it's more to compensate for various injuries. Most people I encounter, personally and professionally, would be in the same area. What do you think? Do you think self love is appropriate when it is "for God's sake"? Where do you think you are in those degrees?
