After responding to the article on the autonomy of local churches at The Christian Watershed, I am happy to commend to you this article at the same site.
On being like Athanasius:
We need a modern-day Athanasius; we need many people to act like an Athanasius in their own communities. We need Christians who are willing to stand on the orthodox principles of the faith even when it costs them personally…
But all of this begins with studying the orthodox tenets of the faith. If we don’t know our faith then how can we stand up for it? Athanasius was able to defend the faith because he understood the faith and he understood the implications. Likewise, he did not defend the faith so he could make a name for himself. He did not defend the faith so he could get a nice book deal that would bring in money. He did not defend the faith so people would be in awe of his knowledge. Instead, he defended the faith because he loved God. He learned the faith because he loved God.
And, coincidentally, if you are interested in learning more about some of the great Christian thinkers of the past, as well as simply understanding the Christian faith, I commend this study to you as well.
