Trinity, Overlooked or dismissed
“For most people and, sadly, for most Christians also, the Trinity is the great unknown. The Trinity, to use a familiar equation, is viewed as a riddle wrapped up inside a puzzle and buried in an enigma. A riddle, for how can any entity be at the same time multiple (three) yet singular (one)? A puzzle, for the Trinity is so clearly contrary to any rational thought as not to warrant a second thought from sensible people. An enigma, for even if the Trinity could be understood, of what practical value, even what religious value, would it have for ordinary people.”
