Under Emperor Constantine in the Roman Empire, by imperial decree, everyone was baptized as an infant and understood to be a Christian. To become a Christian was difficult because everyone else was already considered a Christian. The difference between the Christian and the “Christian life” became blurred. Rather than help the Church, this may have hurt it.
There were Christians then who wanted to become seriously devoted Christians and made a personal decisions to give up everything to follow and serve God. To pursue a higher calling then meant becoming a monk or a nun and renouncing materialism and marriage. Monasticism grew. People even made vows to the evangelical counsel of poverty, chastity and obedience. In effect, this raised the bar higher. There was now more things to differentiate mainstream cultural Christians from those who sacrificed everything and committed their whole life to serve God.
In the Protestant and evangelical world, we don’t have monasticism. So how can we express our devotion to the Lord Jesus without hiding away in a monastery? Can we boldly bring our Christian faith into the workplace without sacrificing our total devotion to God? It’s not easy, but I think it can be done.
