I was reading the Thursten & Attwatter Edition of Bulter's Lives of the Saints on the 9th of May, and came across a passage on Saint Gregory Nanzianzen that seems to apply to our day and age.  It is said that during his life he "rekindled the torch of the true faith in Constantinople when it was well-nigh extinguished and kept it burning at the Church's darkest hour."

Here is a little bit about his life:

"The Arians and Apollinarists pursed him unrelentingly with slanders, insults and even personal violence.  They broke into his church; they pelted him in the streets and dragged him before the magistrates as a brawler.  He comforted himself by reflecting that if his adversaries were the stronger party, he had the better cause; though they had the churches, God was with Him; if they had the populace on their side, the angels were on his."
