10. Diocletian’s Division of the Roman Empire
Diocletian recognized that the empire was too big/large for one man to rule
He formed the tetrarchy by dividing the empire in half, the Western part, which was centered in Rome, and the Eastern part
After Diocletian died, a civil war broke out in the West between Constantine & Maxentius as to who was going to be the Emperor in the Western half of the Empire

11. Chi Rho: The Greek Monogram for Christ
On his way to Rome, Constantine & his army saw a miraculous vision in the sky—a Cross with the following words around the Cross:
In hoc signo vinces (“In this sign, you shall conquer”)
Even though Constantine was not a Christian, he knew of the Christian faith & understood that this was a sign from God
Constantine had his soldiers paint on their shields the Greek monogram for Christ, the Chi Rho, as they marched into battle against Maxentius
Constantine was victorious!

12. The Edict of Milan
Soon after Constantine became Emperor, he pass an edict of toleration for the Christians—known as the Edict of Milan (313 AD)
The persecution against the Christians that was enacted by Nero in the year 64 AD was completely eradicated—it was perfectly legal to be a Christian in the Roman Empire
The Edict of Milan legalized the Catholic faith, but he allowed the pagan faith to remain

13. The Heresy (false teaching) of Arianism
Soon after, a priest named Arius was teaching that Jesus was not God; rather, Jesus was just a creature of God
This heresy was known as Arianism (named its founder)
The Bishops of the Church met in for the Council Nicaea in 325 AD and did two things…
They condemn Arius’ teachings; Arius was wrong & Jesus was God, co-eternal with the Father
The Council Fathers formulated a creed—a written statement of what the Church actually believed, which we recite at Mass to this very day (i.e., the Nicene Creed)

He was an unmatched thinker & theologian for the next 800 years

16. St. Monica (Mother of St. Augustine)
In his early life, St. Augustine led a very immoral life & one away from the teachings of the Church, much to the chagrin of his mother, St. Monica
She prayed constantly during his life that one day the light of Christ would come into her son’s soul & would embrace the faith
Augustine converted to the faith & became bishop of the city of Hippo in North Africa in the year 395 AD
