So you have 2 separate people groups who have differing cultures and beliefs forming different congregations. They would have differing styles of worship, maybe preaching, how they socialized, what they ate.
But the point is, both sets were true Christians. Those perimeter items didn’t make one better than another.
Today, we have several denominations here and various churches in different countries, all doing things a bit differently, but we all believe in the same Jesus.
We read the same bible, believe in the death and resurrection of Christ for the forgiveness of sins, so what we have today, isn’t much different from the early church.
So let’s do what the early church did. Let’s not wait for persecution to scatter us and drive us to preach. Let’s not sit around all comfortable, not wanting to work too hard, just waiting for the rapture.
Let’s carry out the great commission and “We can see a great number of people turning to the Lord”.
