What you say is true, kosta50, all forms of lack of love in the church are shameful. I suppose I am less bothered by the argumentativeness of many Orthodox because of my experiences in the Anglican/Episcopal church. For example, a few years ago a fairly radical (women priests, etc.) faction in the church where I grew up took over and began a campaign of snubbing and social exclusion calculated to drive away the more tradition-minded members of the congregation, including my own parents. So that sort of thing does bother me even more than open bickering. But I do agree that bickering is not what the Church is meant for.
You may wish to read this famous public address on this issue. I hope it gives you some insight into waht I am talking about.
A bickering church is a weak church. A bickering church is a church where pride rules and God's light is absent. A bickering church is where mercy and forgiveness are not there. A bickering church is ruled by greed and judgment. A bickering church is a failed church.
