The skill is to lift our ordinary ways of thought and speech to reflect our approach towards the wonder of God. This is surely what Jesus was doing through the parables and his constant address to God as Father. It was a vernacular style. But that did not annul the otherness of God. When we sing the great classic hymns we are often using what was, for the writers, ordinary speech but is for us antique poetry.
Language is just part of the story.
As soon as worship becomes superficial or trivial or an entertainment it ceases to be worship of God and becomes a communal activity to satisfy a social need. That could still be a valuable way of gathering people together, but we are kidding ourselves if we call it worship of God. We worship God to climb Sinai. Or to walk the Via Dolorosa. Or to enter the garden at dawn.
