Some ideas and practices are like Sacred Cows. Too much is at stake to challenge them, so we just pretend we are OK with it when really we are not; we just couldn't be bothered with the fight. The people of Ephesus were hugely invested in the Temple of Artemus (It was after all one of the 7 wonders of the ancient world) and when Paul challenged them they went berserk and rioted. The hundreds of years of tradition, economic value and entrenched religious thinking made any new thinking impossible. Lets try to stay open minded no matter how long we have been invested in our own particular point of view.
