“The earth is hard and inert, though it revolves very fast round the sun; water is liquid and rapid, therefore people say a current is rapid; air is still more liquid, more rare- fied and more rapid, and therefore it moves very quickly, as, for instance, in the case of winds; light is still more ethereal, more rapid, and in one second it travels over incredibly great distances. If light is so ethereal and traverses immense spaces in the shortest possible time, then what must the created spirit be, and how ethereal and rapid must it be! Finally, what must the uncreated Spirit be--the Lord Himself! How immeasurable must He be! If light in one second moves with such awful rapidity, then how rapidly must the uncreated Light--the Source of all Light and of everything created--move in intelligent created spirits! Finally, how must the Light which created everything embrace all His creatures, all the multitudes of worlds! Glory to Thee, the Light immaterial and uncreated, "which lighteth every man that cometh into the world." [112]”
John of Kronstadt was a Russian Orthodox archpriest and member of the synod of the Russian Orthodox Church. He was a striking and somewhat unconventional figure in his personality but was deeply pious and immensely energetic. He was one of the most internationally famous and beloved Orthodox Christian clerics of his time.
He was born as Ivan Ilyich Sergiyev. From 1855, he worked as a priest in Saint Andrew's cathedral in Kronstadt. Here, he greatly committed himself to charity, especially for those who were remote from the church, and travelled extensively throughout the Russian empire. He was a member of the right Union of the Russian People, but did not commit himself politically. He was already greatly venerated at the time he died.
He was canonized by the Russian Orthodox Church Outside of Russia in 1964 and by the Russian Orthodox Church in 1990. The second largest monastery of St Petersburg (by community size) is dedicated to John of Kronstadt.
