Nick Kennicott considers the delicate pastoral situation of Christians who move from one church to another because of unhappiness with their last church.
Faithful local churches want to grow through the redemption of sinners. Through evangelistic efforts and the consistent administration of the ordinary means of grace, there should be a healthy expectation that there will be new believers joining the church periodically. However, the most significant growth in most local churches is Christians transferring their membership from other local churches. Almost 60% of American churches have an average of 75 members, so it’s refreshing and can be exciting to see new faces with new and different gifts. It is not wrong to want to see the church grow, but it should never be without several important considerations.
There are certainly cases when the discontentment of sheep is legitimate and they have good reasons to leave their church. Sadly, churches can be abusive and authoritarian, or they can be heretical. Additionally, a Christian should have a general desire to be in their church knowing that there is substantial agreement on doctrine and philosophy of ministry. If things change, there may be very legitimate reasons for a believer to look for a new church family. Likewise, Christians are never obligated to remain in a local church and nobody can insist that they must. Church membership is a vital aspect of the Christian life; but, Christians need to be members of a faithful local church, not necessarily any one church that they may have joined at some particular point in time.
