But what do the Scriptures teach about this?
Act 18:24 Now a Jew named Apollos, an Alexandrian by birth, an eloquent man, came to Ephesus; and he was mighty in the Scriptures.
Act 18:25 This man had been instructed in the way of the Lord; and being fervent in spirit, he was speaking and teaching accurately the things concerning Jesus, being acquainted only with the baptism of John;
Act 18:26 and he began to speak out boldly in the synagogue. But when Priscilla and Aquila heard him, they took him aside and explained to him the way of God more accurately.
Act 18:27 And when he wanted to go across to Achaia, the brethren encouraged him and wrote to the disciples to welcome him; and when he had arrived, he greatly helped those who had believed through grace,
Act 18:28 for he powerfully refuted the Jews in public, demonstrating by the Scriptures that Jesus was the Christ.
This Apollos wasn't refused fellowship because his doctrine wasn't perfect. He was taken under wing, as a brother who loved Jesus, and taught the things more perfectly. He was given fellowship, he wasn't denied fellowship.
Now if a brother were walking disorderly, sinfully &c then I think we have reason for disallowing fellowship.
- Peace
If a brother, already a member of the church, were walking disorderly, sinfully, &c no fellowship will be disallowed IMMEDIATELY. Maybe you know this, maybe not, but I need to complete the statement.
The said brother will be prayed for by the church (if his disorderliness and sin is common knowledge to the church), after which the church will observe the rules of discipline provided for by its founder, culminating in disfellowship and being cut off from the church with the end in view of restoring the erring brother, and of accepting him back IF he repents and comes before the church in repentance.
If the sin and disorderliness is private and known only to very few in the church, then he will be dealt with discreetly with the purpose of preserving his/her and his/her family's integrity up to the point of discipline according to Scriptural guidelines, keeping the matter as privately as possible thus avoiding embarrassment for the member, and keeping the door to repentance and reconciliation open.
These are the details (at least in my PB neck of the woods) that we follow, patterned after the constitutional generality provided by the Lord in Scripture.
Now, as for a professing Christian wishing to join our church, and carrying his own doctrine, which we deem incomplete, or not compatible with what we believe and hold on to, as a church, and who DOES NOT accept the teaching, no church membership will be possible for him, neither will the fellowship be sweet (it will always be cracked because of doctrine).
When I joined the church here, I was willing to learn the Doctrine of Grace, which I have already accepted as Scriptural truth, and unlearn what was drilled to me by my former Arminian pastors, and the Arminian seminary I went to.
