As I see it, true Christianity is much different from the Christian religion that many condemn. Indeed, true Christianity often attracts nonbelievers, rather than offending them.
This real Christianity includes serving others by giving to the poor, helping the sick, and in general caring for one’s fellow human beings.
True Christianity includes practicing love for others, even one’s enemies, as Jesus and the Apostle Paul both taught according to the New Testament gospel biographies of Jesus and the New Testament writings credited to Paul.
Fun fellowship is also a part of it. The joys exhibited by Christians attract others to join.
This fellowship can take many forms. In fact some Christians fellowship with other Christians in their family, neighborhood, and workplace and don’t regularly attend a particular denominational church in a formal church building.
Evangelism is also a part of true Christianity. But it is largely evangelism in the sense of answering questions from others who want to know the reasons for the joy Christians have. Real Christianity attracts others.
By living a Christian life where we are and where we travel to, we spread Christianity by our example, rather than by formal evangelism.
Teamwork is a key to it. Rather than a pastor, missionary, deacon, elder, or other Christian leader doing all the work, in a true Christian church each believer is to do an honest day’s work as part of the body of Christ. New members may not have the training or ability of those who have been taught well, but each can contribute in some way.
This teamwork in service doesn’t necessarily mean serving inside a four walls congregation either. Even the numerous tasks that need done in a given church don’t require a lot of hours from every member. Therefore, most Christians do most of their Christian service outside the church building in their community and in other communities.
I think this is one reason many congregations write in their weekly bulletin or post somewhere in their church building words something like “enter to worship, leave to serve.” This makes it clear than their time in the church service is for worship, but after leaving, the remainder of the week is time for service to God (the highest righteous authority) and others.
But getting adequate rest is part of Christianity, too. One ought not to be a workaholic. Indeed, each member of the flock doing their own share of the labor, makes it go more smoothly.
Summary -- and Tolerance for Other Faiths
In simple terms, loving and caring for oneself and others is what true Christianity is all about. And I think even those who do not profess to be Christians can practice true Christianity.
As Romans 2:14 puts it in the King James Version of the Bible:
“For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:”
Those are very wise words from the Apostle Paul’s letter to the Romans.
Yes, atheists, agnostics, Buddhists, Hindus, Muslims, and followers of other religions may be practicing a form of true Christianity. I’m confident some do through the grace of God.
I am happy to call them honorary Christians for obeying God (the highest righteous authority) without even knowing it.
Enjoy God’s blessings!
