Should Christians use images?

Today one of my college students sent me this question:

_________________________________
Hey... got a question for ya, I'll try to keep this short:

I attached a picture of the triquetra, one of my favorite trinity symbols. I was recently looking at the symbol on google, trying to find one that I think would look good on a t-shirt or something.

However, in what could only be God trying to compel me to delve further into religion, I discovered that in Acts 17:29, it says, "Therefore since we are God's offspring, we should not think that the divine being is like gold or silver or stone—an image made by man's design and skill." Am I analyzing this way too much, or am I looking at a verse that basically says that I shouldn't, for example, wear a ring with the triquetra symbol on it? If you could maybe clear this up for me, that'd be yet another awesome point for ya. Thanks!

To which I answered...

"Evangelical" has apparently been left behind to follow "Antichrist"

2018 Note: After re-reading this post, I agree with the substance of it for the most part. But I do come off here as a bit of a condescending twit. So, read at your own risk. I leave it up as a monument to personal growth.

On July 05 2006 I posted a critique of the anti-Christian video game (made by Evangelical Christians) called "Left Behind" (in honor of the novel series of the same name). Today, I received a comment from a blogger named "SJR" who claims to work for Left Behind video games. I want to post his comment, my response to his comment, and my original article:

--------------------------------------
SJR's complete comment (with the points I want to comment on numbered in brackets []):

This statement is posted from an employee of Left Behind Games on behalf of Troy Lyndon, our Chief Executive Officer.

There has been in incredible amount of MISINFORMATION published in the media and in online blogs here and elsewhere.

Pacifist Christians and other groups are taking the game material out of context to support their own causes [1]. There is NO “killing in the name of God” and NO “convert or die” [2]. There are NO “negative portrayals of Muslims” and there are NO “points for killing” [3].

Please play the game demo for yourself (to at least level 5 of 40) to get an accurate perspective [4], or listen to what CREDIBLE unbiased experts are saying [5] after reviewing the game at www.leftbehindgames.com/pages/controversy.htm

Then, we’d love to hear your feedback as an informed player. The reality is that we’re receiving reports everyday of how this game is positively affecting lives by all who play it [6].

Thank you for taking the time to be a responsible blogger [7].

My response to SJR:

WWGD: What Would Gramsci Do?

I read an article the other day written decrying how atheist secularism has invaded our University systems and turned them into Godless cesspools of rotting postmodernity. It ponted out how many Universities (even Religious ones!) have a systematic method of "catechesis" designed to make the student body seriously question, if not deny, the traditional values espoused by most traditional religions. And, judging from my experience at six Universities, they were largely right about the method, even if they were wrong about the extent (there are still lots of faithful academics out there who have not bowed their knees to the Baals of secular culture). And what is supposed to be the reaction of "good Christian" parents and children? Hide! Vacate secular universities for home schools and "safe" Bible colleges. But is that the right response for people who believe that Jesus came to redeem and reconcile ALL creation to the Father?
