How do we know the doctrine of communication is true?

We know the doctrine of communication among believers is true from the Scriptures, which stress the necessity of communication for true fellowship. The Apostle John, for instance, prioritizes personal communication in 3 John, signifying that written communication, while valuable, is not a substitute for in-person interaction. Furthermore, throughout the New Testament, we see apostles like Paul expressing their desires to visit and communicate with the churches, emphasizing the significance of sharing faith and spiritual gifts in person. This biblically rooted principle illustrates the essential character of communication in building a mature and loving church.
