This is interesting, if unsurprising.
Orthodox stress that worship and theology in Orthodoxy are harmonious. Typically, though, more attention is paid to worship—especially regular participation in the prayer of the Church, in rites and rituals—and much less to the content of the faith, to theology, resulting in a gap between worship and theology suggested by the examples here.
Though the examples may not come from much of a study, there’s something very true here that could just as easily be written for and from a small-o orthodox perspective.
The fact is that in life—actual life—most of us are still trying to figure out what it is we’re talking about. We all probably have at least a little heretic in us.
