As promised, here is my review of Dan Brennan's book:

Dan Brennan’s ground-breaking book “Sacred Unions, Sacred Passions” courageously attacks the oldest and most difficult wall dividing the Christian church—the wall between male and female. Brick by brick, he dismantles the notion that intimate, even passionate, friendships between men and women are impossible and dangerous. He builds instead an eloquent case that male/female friendships are healthy, and necessary for becoming whole and complete people.
