(On the difference between secular BDSM and "Christian BDSM")
They are different since there is a specific spiritual component to their relationship. The Master and submissive/slave worship, pray and grow together as Christians. The Master is head of the wife. She submits to Him. Christ is the head of the church. Master and submissive are both in submission to Christ. A Christian submissive’s first responsibility is to God and His commandments. Unlike her secular sister, a Christian submissive should not participate in something against God’s teaching, even if ordered by her Dominant/Master.
