Before Constantine made Christianity the official religion of the Roman Empire....
Christians were only 5% of the population. Jews and adherents to Judaism before that were a very small part of the population.
God has never been in it for the numbers.
According to Jesus the world already stands condemned...but He did come to seek those who belong to him and were lost.
Where society is much easier to navigate when the population seeks after righteousness...it's not going to ever remain that way.
Hey brother, just a note.
Galerius issued the Edict of Toleration in 311. This ended the systematic persecution of Christians.
Constantine called the Council of Nicaea together in 325. This served to 1) address the issue of Arianism (Christ is not divine) and to establish order in the church that mirrored the Roman government (popes, cardinals, bishops, etc).
It was actually
Theodosius in 380 that made Christianity the official religion of Rome. By that time an estimated 10% of the Roman empire was Christian. That may not seem like a lot but the church represented the largest homogeneous group in the entire Empire. In effect: even though they were heavily persecuted, believers had conquered the Empire of Rome from within.
Where they went wrong is this: they took the offer from the government and agreed to represent the Empire. Yet, the church already had a mandate to represent another government: the Kingdom of God. They gave up their first, heavenly calling to take on the second, terrestrial one.
