I am blessed with many spiritual soul-sisters. Many of them are Catholic or Anglo/Catholic, but some of them are Protestant.
I first came accross the idea of spirital friendship years ago at a conference in Montreat North Carolina & even bought a book about the topic.
Spiritual sisterhood is different from spiritual direction. The latter is much more formal. Spiritual sisterhood occurs when two women just have a connection that is formed & maintained by their shared spirituality & love of God
Actually, love of God is imperative to the formation & maintainance of a spiritual sisterhood. I have learned that ANY relationship worth maintaining MUST have God involved & this includes friendships. Any friendship I have that does not have God at its center is pretty much an acquaintance, no matter for how long I’ve known the person or how often she & I might see each other face-to-face. The beauty of technology is that people who have such spiritual connections can much more easily maintain such connections. Plus , the Internet, if used wisely, can be a wonderful source to meet new spiritual sisters. For instance I am Fabecbook friends with a great young woman whom I have never met in person but with whom I communicate almost daily via Facebook & e-mail.
