Ebor et al:
Unfortunately, the realities of written communication in the absence of audible and visible context, leads to many times more potential for misunderstanding. Too, certain words, perfectly legitimate otherwise, have been lent sociopolitical stigma that degrade those words' perfectly acceptable meaning.
Take for example the word "patriarchy." In today's cultural climate it conjures up images of wife-beating, oppression and bigotry. But why? Is it because the word itself refers to that? No. It's because those who oppose traditional (small-o) orthodox belief about the Trinity, the priesthood and the home have been successfully in reengineering its meaning.
Christianity is essentially a patriarchal religion. We believe that the source (arche) of the Godhead has been revealed in Jesus Christ as God the Father (pater). From the Father the Son is begotten. From the Father the Spirit proceeds. From the hypostasis of the Father is the unity of the Godhead. So, the priesthood becomes an icon of the Godhead. And relations between husbands and wives reveal the image of the Triune God in whom they were/are created.
So when patriarchy is used in its modern perjorative connotations, those traditional, orthodox Christians (of whatever church affiliation) are right to think their Faith has been challenged. And they are right to question the challenger. Nor is it, despite the sensitivity of one's audience, wrong to label such modern attacks on the Faith as heresy or schism. It is stating the truth.
(In fairness, I could also discuss the degradation of the word "liberal.")
The truth, we are commanded, is to be spoken in love. The internet does not make for realistic contexts of love. Disembodied "voices" are not those whom we can embrace. Further, our American context makes any absolute statements regarding truth out to be personal, vicious attacks While we may have to reckon with that context, we must also recognize that such thinking ultimately results in censorhip.
In some ways it is an irresolvable dilemma. Those called heretics and Pharisees, sure don't want to be called that, and given our cultural contexts, even if it is true, respond by challenging the other person's charity. But truth and charity do mix. Indeed, they're essentially entwined in Christian discussion. Sometimes truth hurts. Sometimes love must cut.
Always we must remember first that we are worse sinners than those with whom we agree.
