After Jesus had declared that He would build His church on the truth of Peter’s noble confession, He went on to say, “I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven” ( Matthew 16:19 ). Later, addressing all the disciples, our Lord repeated the words, “Whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven” ( Matthew 18:18 ).
Jesus gave Peter “the keys of the kingdom of heaven,” not the keys to heaven.1 A key was a badge of authority ( Luke 11:52 ), and then as now was used to open doors. Peter used the keys Christ gave him to open the door to the Jews on the Day of Pentecost ( Acts 2 ), to the Samaritans after the preaching of Philip ( Acts 8:14-17 ), and to the Gentiles after the Lord had sent him a vision and an appeal from Cornelius ( Acts 10 ).
The concept of “binding and loosing” found in Matthew 16:19 and Matthew 18:18 was commonly used among the Jewish people in relation to the authority of the rabbis to forbid and permit certain practices. Jesus gave Peter and the apostles authority over both the doctrine and practices of the first-century church. Through the leading of the Holy Spirit, they would be given wisdom to know what to forbid and what to permit.
This authority, not on exactly the same level as during the apostolic era, still resides in the leaders of the local church. They may not receive the same kind of supernatural guidance as the apostles did,but they possess the entire New Testament along with the direction of the Holy Spirit. 2 Therefore, when church leaders discipline a church member who promotes incorrect doctrine or is involved in evil behavior, they act with divine approval. They are carrying out God’s will, and what they do is ratified in heaven. Since their authority is not ultimately derived from their personal qualities or their office but from Scripture and the instruction of the Holy Spirit, they should exercise it humbly and prayerfully.
