Reading 1 Acts 11:19-26
Those who had been scattered by the persecution
that arose because of Stephen
went as far as Phoenicia, Cyprus, and Antioch,
preaching the word to no one but Jews.
There were some Cypriots and Cyrenians among them, however,
who came to Antioch and began to speak to the Greeks as well,
proclaiming the Lord Jesus.
The hand of the Lord was with them
and a great number who believed turned to the Lord.
The news about them reached the ears of the Church in Jerusalem,
and they sent Barnabas to go to Antioch.
When he arrived and saw the grace of God,
he rejoiced and encouraged them all
to remain faithful to the Lord in firmness of heart,
for he was a good man, filled with the Holy Spirit and faith.
And a large number of people was added to the Lord.
Then he went to Tarsus to look for Saul,
and when he had found him he brought him to Antioch.
For a whole year they met with the Church
and taught a large number of people,
and it was in Antioch that the disciples
were first called Christians.
If Barnabas and Paul could belong to a Church -- why can't you?
They didn't belong to a "church". They were members of and ekklesia. The Catholic concept of "church" doesn't exist in scripture.
