Is a person’s belief about spiritual gifts essential to fellowship????
Well, my answer depends on the attitude of the person we are dealing with.
Some people who do not believe in spiritual gifts are just without knowledge of them, … their value, their importance, or how they operate. These folk would be civil in any discussions regarding the nature of gifts and miracles continuing.
However, others are belligerent toward anyone who believes in spiritual gifts continuing to operate in the Church. They argue that those who believe in miracles and supernatural gifts are stupid, crazy, deceived, liars, or that they are demonized.
As one who believes that all of the gifts and manifestations of the Holy Spirit are for the Church today, I would find it difficult to fellowship with someone who would be so crass to call me any of these things.
On the other hand, to deny that spiritual gifts and manifestation of the Holy Spirit are for today, or that miracles occur today, causes a credibility problem with the Scriptures. Most of the promises of God become absolutely meaningless as one embraces the doctrine of cessationism. God is a supernatural God and prayer, according to the teaching of Scripture, is an expectation of something miraculous and supernatural. If we cannot expect God to do miracles then prayer can become a powerless ritual, just something you do to be religious.
I would find it difficult to fellowship with someone who in effect denies that the God of the Bible cannot be trusted to keep His promises.
