William MacDonald emphasizes the distinction between the New Testament understanding of a bishop and the modern interpretation. In the early church, bishops were mature Christians serving the spiritual needs of their local congregations, rather than appointed dignitaries overseeing multiple churches. MacDonald highlights the qualifications and duties of bishops, stressing that they should be humble servants rather than figures of authority, and that their selection is ultimately guided by the Holy Spirit. He also points out that the church's recognition of elders should be based on their spiritual qualifications rather than worldly success. The sermon concludes with the importance of the church's attitude towards elders, advocating for respect and support for their leadership.
