Warning to Christians: There may be churches that will bless your Blackberry, but your favorite morning workout may undermine your faith. In a recent blog post, Dr. R. Albert Mohler, Jr. president of the Southern Baptist Theological Seminary, examines the argument that practicing yoga may be in direct conflict with the values of Christianity. "Yoga begins and ends with an understanding of the body that is, to say the very least, at odds with the Christian understanding," Mohler writes.
