We are presently being "treated" to some of the rhetoric that some protestant evangelicals muster in their attempt to discredit Catholicism.
There will always be those who will approach these discussions with the single minded purpose of discrediting beliefs they do not hold. These people are passionate about "their position" and not passionate about what is important - the truth.
This is evidenced by their stark refusal to accept solid arguments that undermine their positions. Its almost as if reason does not matter and they cling to their position despite it. A recent example is the whole Matt 1:25 thing. The arguments to this point are decisive - this text, in and of itself, does not warrant a conclusion that Mary and Joseph ever had intercourse. The "until always means a state transition" argument has been dissembled with precision and clarity. But this seems to matter not one whit. But there may be further arguments. And that is but one example.
I would like to encourage those who have taken the high ground to stay there. And I encourage the others to take that same route.
At the end of the day, I believe those who use rhetoric may indeed "win" for a day. I am not so naive to think that rhetoric does not sway people - it does.
But I have to believe that sober, careful, and correct arguments determine the long term outcome. There are doubtless lurkers in these forums that are "shopping" for something to believe. I am hopeful that these people, who are not hopelessly trapped in a "my present belief must prevail even if it is proved to be wrong" mindset, can advance in their search despite the braying of the rhetoric merchants.
People who, with humility, accept that life is a 70 year process of correcting mistaken ideas , are the ones who can change the world in the long run.
