The primary function of the Parish Finance Council is to assist and advise the parish priest in accordance with Canon 537 of the revised Code of Canon Law. Each parish is to have a finance council which is regulated by universal law as well as by norms issued by the diocesan bishop; in this council the Christian faithful aid the parish priest in the administration of the parish goods with due regard for the prescription of Canon 532 (the parish priest represents the parish in all juridic affairs). To this end the parish priest has established a Finance Council of four persons who enjoy a consultative voice. Membership of the finance council is at the discretion of the parish priest. Its four members, not including the parish priest, constitute the parish finance council. Simultaneous membership of the finance council and the parish council is not permitted.

The Gift Aid Secretary Mr Tim Coyle and the Cathedral Administrator Mrs Mary Manners are ex-officio members of the Finance Committee and they also attend the meetings. Membership of the committee is on a three year term renewable for not more than a total of three terms.
