[Sidenote:  Constantine’s interference.]

The Eastern Emperor, Licinius, let the dispute take its course.  He was a rude old heathen soldier, and could only let it alone.  If Eusebius of Nicomedia tried to use his influence in favour of Arius, he had small success.  But when the battle of Chrysopolis (323) laid the Empire at the feet of Constantine, it seemed time to get the question somehow settled.

CHAPTER II.

THE COUNCIL OF NICAEA.

[Sidenote:  State of the Empire.]

For nearly twenty years after the middle of the third century, the Roman Empire seemed given over to destruction.  It is hard to say whether the provinces suffered more from the inroads of barbarians who ravaged them almost at their will, or from the exactions of a mutinous soldiery who set up an emperor for almost every army; yet both calamities were surpassed by the horrors of a pestilence which swept away the larger part of mankind.  There was little hope in an effete polytheism, still less in a corrupt and desponding society.  The emperors could not even make head against their foreign enemies.  Decius was killed in battle with the Goths, Valerian captured by the Persians.  But the Teuton was not yet ready to be the heir of the world.  Valerian left behind a school of generals who were able, even in those evil days, to restore the Empire to something like its former splendour.  Claudius began by breaking the power of the Goths at Naissus in 269.  Aurelian (270-275) made a firm peace with the Goths, and also recovered the provinces.  Tetricus and Zenobia, the Gaulish Caesar and the Syrian queen, adorned the triumph of their conqueror.  The next step was for Diocletian (284-305) to reform the civil power and reduce the army to obedience.  Unfortunately his division of the Empire into more manageable parts led to a series of civil wars, which lasted till its reunion by Constantine in 323.  His religious policy was a still worse failure.  Instead of seeing in Christianity the one remaining hope of mankind, he set himself at the end of his reign to stamp it out, and left his successors to finish the hopeless task.  Here again Constantine repaired Diocletian’s error.  The edict of Milan in 312 put an end to the great persecution, and a policy of increasing favour soon removed all danger of Christian disaffection.

[Sidenote:  Constantine.]

When Constantine stood out before the world as the patron of the gospel, he felt bound to settle the question of Arianism.  In some ways he was well qualified for the task.  There can be no doubt of his ability and earnestness, or of his genuine interest in Christianity.  In political skill he was an overmatch for Diocletian, and his military successes were unequalled since the triumph of Aurelian.  The heathens saw in him the restorer of the Empire, the Christians their deliverer from persecution.  Even the feeling of a divine mission, which laid him
