30. By divine institution, some among the Christian faithful are constituted sacred ministers through the sacrament of orders. They are consecrated and deputed to shepherd the people of God, each in accord with his own grade of orders, by fulfilling in the person of Christ the functions of teaching, sanctifying, and governing (Canon 1008).
31. The existence of a physical disability is not considered in and of itself as disqualifying a person from holy orders. However, candidates for ordination must possess the necessary spiritual, physical, intellectual, emotional, and psychological qualities and abilities to fulfill the ministerial functions of the order they receive (Canons 1029 and 1041, n. 1). The proper bishop or competent major superior makes the judgment that candidates are suited for the ministry of the Church (Canons 241, sect. 1; 1025, sect. 2; 1051, n. 1). Cases are to be decided on an individual basis and in light of pastoral judgment and the opinions of diocesan personnel and other experts involved with disability issues.
32. Diocesan vocations offices and offices for ministry with persons with disabilities should provide counseling and informational resources for men with disabilities who are discerning a vocation to serve the Church through one of the ordained ministries.
33. In preparation for responsible leadership in ordained ministry, the diocesan bishop or major superior is to see to it that the formation of all students in the seminary provides for their service to the disabled community, and for their possible ministry to or with persons with disabilities. Formation personnel should consult with parents, psychologists, religious educators, and other experts in the adaptation of programs for ministerial formation.
