I'm not uncomfortable with subjective things but, in the Scriptures, the subjective responses are grounded in some objective truths. The problem, again, with pinning something down as boring is that people can only describe what factors they believe contribute to their boredom (or the people they know) but cannot pin down why it must be characterized as boring. One of the reasons a Supreme Court Justice is forced to simply say "He knows it when he sees it" is because he is unable to objectively point to a Law where we do not have such a problem. I don't believe the analogy is apt because the Law of God makes lust and other indulgences of the flesh very clearly moral violations. The problem here is that nobody has provided any Scriptural warrant that commands a man not to be perceived as boring. How could we apply the general equity of the Law to do so? How would we rebuke a Pastor for being "boring"? Again, we can apply many objective criteria by which a Session could tell the man specifics about style, not being pedantic, not being prideful, expressing direct concern for the listener, etc. But, if a Session, merely told a man: "I can't tell you anything except that I think you're boring," then what, precisely, is a man supposed to do with that kind of criticism? When you're dealing with self-improvement, you have to work on tangible qualities and that list that Pergie provided is tangible but those problems are not unique to being perceived as boring. Frankly, for many of them, my reaction would be indignation or frustration and a whole set of other emotional reactions rather than settling on boring. See above. I would also add that the emotional criteria you mention might be dangerous if the goal of the preacher is focused upon "not being boring" but receiving the benediction from the congregation that he is "exciting." This points, in fact, to a poverty of any other number of elements of Worship. For instance, "exciting" and "dynamic" are used as primary criteria by many to select songs and tunes and many believe they are only worshipping when they feel "excited" or "worshipful". When I'm worshipping God in song, for instance, I don't always have an emotional reaction to singing nor do I worry if I do not. Yet, when reading a Psalm responsively yesterday in Worship, I was very moved by it because it caused me to reflect on the objective Truth of my status in Christ.
