While all members of the Church are equal in authority to rule, no two have exactly the same measure of cultivated ability in the exercise of their charism and office. Thus all decision-making according to the will of God in community arrives at consensus in a ministerial way according to the Apostolic Rule of Faith in order to incorporate the contributions of all, regardless of their capacity.
