I wonder who made that throne at the back of the RCC churches?
Craftsmen made the altar and built the church. But he, the craftsman worked the wood; Christ makes it His throne when he comes to "abide with us" (John 6:57; your number is probably off by one).
Also, the purported irony about "back of the Church" is only funny for someone ignorant of basic architecture of temples and palaces, and especially the Solomon's temple. Yes, people enter any palace or temple and walk their way to the throne, or the sanctuary, erected at the opposite side.
