The pagans are just as bad. Where are the blood sacrifices? Where are the temple prostitutes? Where are the Baals, the Asherim, and the Molechs? Where are the amulets, wizards, oaths, superstitions? Where are the philosophers and the myths? Where are the pantheons, the idols? And, where is the persecution? I've been waiting, but no one has dragged me to the temple and given me a choice of offering a pince of incense to an idol and denying Christ or death. It's all very disheartening, really. It used to be that men believed in gods. Then man believed in the true God. Then man began to believe in himself. Now man believes in nothing, and not even in nothing. Man simply doesn't give a flying flip about belief.
That said, the contemporary accounts we have of early Christians do not set them physically apart much from the pagans surrounding them. Their differences were only seen by those who looked for them. And it is the same today. While we have worldly Chrisians, and while Christians are weaker than they have been, we need to recall the words of the ancient fathers, how many of them longed to live in these and the end times, and how for us the struggle will simply be to hold on to our faith. We are incapable of great deeds. But the opposition is so great for this one little desperate act that it will be counted by God to be worth more than many great deeds--so said many of the ancient fathers.
So, we can go on and on comparing, or we can follow the patristic advice and stop making comparisons altogether and do our best to do what God has given us to do. It is sufficient for us--not just for squeaking by into Heaven, but for many to obtain crowns.
