The Chancellor of Spiritual Affairs is an episcopal vicar who acts in the name of the Archbishop for those matters which relate to the teaching and sanctifying offices of the Church. The teaching office of the Church is manifested primarily in the mission of evangelization and catechetical instruction. The sanctifying office of the Church is manifested primarily in the Sacraments and divine worship, especially as it is evidenced in parishes, missions and institutions that the Church's faith is preached and taught according to Church norms.

It is proper to this office to ensure the lawful celebration, administration and reception of the Sacraments and to develop pastoral norms and policies. The Chancellor of Spiritual Affairs is also responsible for ensuring that the pastoral practices of the Archdiocese are in accordance with the universal and particular law of the Church.
