their duties properly because of the increasing burden of age or some other serious reason, are earnestly requested to offer their resignation from office either at their own initiative or upon the invitation of the competent authority." The age of 75 was suggested, and John Paul II had these provisions incorporated in the Latin Church's new 1983 Code of Canon Law. Article 401.1 of the 1983 Code of Canon Law states that "A diocesan Bishop who has completed his seventy-fifth year of age is requested to offer his resignation from office to the Supreme Pontiff, who, taking all the circumstances into account, will make provision accordingly". On 15 February 2018, Pope Francis established the same rule for non-cardinal bishops serving in the Roman Curia, who had previously lost their positions automatically at 75. Roles A "diocesan bishop" is entrusted with the care of a local Church (diocese). He is responsible for teaching, governing, and sanctifying the faithful of his diocese, sharing these duties with the priests and deacons who serve under him. To "teach, sanctify and govern" means that he must (1) oversee preaching of the Gospel and Catholic education in all its forms; (2) oversee and provide for the administration of the sacraments; and (3) legislate, administer and act as judge for canon-law matters within his diocese. He serves as the "chief shepherd" (spiritual leader) of the diocese and has responsibility for the pastoral care of all Catholics living within his ecclesiastical and ritual jurisdiction. He is obliged to celebrate Mass every Sunday and Holy Day of Obligation with the intention of praying for those in his care, assign clergy to their posts in various institutions and oversee finances. A bishop is to have a special concern for priests, listening to them, using them as counsellors, ensuring that they are adequately provided for in every way, and defending their rights set forth in the Code of Canon Law. Latin Catholic bishops also must make regular ad limina visits to the Holy See every five years. Because of their function as teachers of the faith, it is customary in some English-speaking countries, to add to the names of bishops the postnominal title of "D.D." (Doctor of Divinity) and to refer to them with the title "Doctor". Only a bishop has authority to confer the sacrament of holy orders. In the Latin Church the minor orders were abolished after the Second
