Every Knight is by definition a Lay Apostle; one who aims to promote the Catholic Church by Christianising his own environment.

By his words and actions, a Knight can influence those with whom he associates and make a positive contribution to the Church's Social Teaching.

As a member of the Order his obligation also extends to joining with fellow Knights in those activities which rely on organisation and commitment for their success.

 No Knight should lose sight of his obligation to assist the clergy of his parish, in every way possible.

On every Catholic there lies the obligation to contribute to the support of his pastors.

On the Knight there rests a greater responsibility; which is to be discharged by providing willing assistance to the clergy in their duties, whenever that assistance is required.

The harmonious relationship which exists between the Knights of St Columba and the Clergy is apparent by the co-operation and support provided by the Hierarchy.

From the Order's earliest years the Hierarchy has appointed one of their number as Ecclesiastical Advisor to the Order; the present one being the Rt Rev Malcolm McMahon, Bishop of Nottingham.
