Roman Catechism 17.16

Chapter 17 — Part II: The Sacraments — Confirmation

Section 16. Balsam, the door of which is most pleasant, can signify nought save that the faithful, when made perfect by the grace of Confirmation, diffuse around them such a sweet door of all virtues, that they may say with the Apostle: We are unto God the good odour of Christ. Balsam has also the power of preserving from corruption whatever it is used to anoint. This property seems admirably suited to express the virtue of the Sacrament, since it is quite evident that the souls of the faithful, prepared by the heavenly grace of Confirmation, are easily protected from the contagion of sins.
