But what would be the point?
There is a point. If you see someone that you think is a brother but you see his faith clouded by untruth, you want to be a light to that person. I don't say that in denial of my own many spiritual weaknesses because I have many. I have been unfaithful to fellowship at my church and have not impressed upon my oldest kids the importance of going to church. So now that they are older they all have jobs on Sundays and seem to be drifting away.
I DO get the point about disagreement in faith and love. But - and I fear I am flogging a dead horse here -- what seems to happen far too often is that ONE point is put up, and when an attempt is made to explore it, a host of other points are brought up before the first point is dealt with usefully. Earlier this fall (no, not THAT fall - I'm still in that one, or would be if it were not for the surpassing grace of God in Jesus - I mean the seasonal one ;-) ) Someone put up the argument, "Why not go straight to IHS?" and when the beginning of a response was attempted, he went directly to, "We shouldn't pray to dead people." And, of course, the result is that NEITHER point gets the attention it deserves.
As for your other remarks, any Christian parent or clergydude who thinks he's done a good enough job is in serious peril. A friend of mine once said, "God, has no grandchildren," and we can pray that God, being a whole bunch smarter than we, knows how to approach our children and teach them His love.
But you're also right that the log in my eye, while it clearly needs attention, does not toally blind me, and obstructed though my vision may be, still I may be able to see something wrong out there.
So I'm not disagreeing with the idea of discussion or of the articulation of disagreement. What I do have a problem with is the presentation of points of disagreement as a kind of artillery rather than as things we might look at together.
And it's a general complaint, not one levelled at you in pertiklar.
