How do we know that titles like Reverend are inappropriate for Christians?

In Matthew 23:8-11, Jesus instructs His followers not to take on titles such as 'Rabbi,' 'Father,' or 'Master,' emphasizing that all are brethren and that the greatest among them shall be a servant. This affirms that the attempt to elevate oneself through titles contradicts the essence of Christian leadership, which is founded on humility and service rather than hierarchy. The New Testament calls for Christians to collectively work toward edification rather than distinction, showcasing the unity of all believers under Christ's lordship.
