Греко-римское paganism, developed and powerful system of idolatry, known to history, after three hundred years of fight yields to christianity and dies from incurable illness, acknowledging: "you won, Galilaean"! The ruler of the civilized world lays the crown to the feet of crucified Jesus from Nazareth. The successor of Nero, Домициана and Диоклетиана appears in emperor's purple on the Nicaea cathedral as a defender of church and occupies the gilded throne on the nod of bishops on that scars are visible yet from persecutions. Despised sect that, as to her Founder in days His humiliation, it nowhere to bend down a head, ascends to higher state power, begins to use the prerogatives of heathen priestliness, becomes rich and mighty, builds from the stones of heathen temples the lot of churches in honour Christ and martyrs, uses wisdom of Greece and Rome, to justify madness of cross, forms civil laws, manages national life and world history.
