Section II. On Character
I. Existence of sacramental character. Three sacraments, namely Baptism, Confirmation, and Order, imprint upon the soul a character, that is, a certain spiritual and indelible sign, whence they cannot be repeated. This is of faith from the Council of Trent: "If anyone shall say that in the three sacraments, namely Baptism, Confirmation, and Order, a character is not imprinted on the soul, that is, a certain spiritual and indelible sign, whence they cannot be repeated, let him be anathema."1 Canon 732, § 1, also teaches this.
II. Nature of sacramental character. The nature of sacramental character is explained in different ways by different authors. Yet all agree in this: that character is a spiritual quality, distinct from sanctifying grace, and is a power by which man becomes capable either of receiving sacred things, as in Baptism, or of handing on sacred things, as in Confirmation and Order (St. Thomas, III, q. 63, aa. 1 and 2). But they dispute, according as they defend either physical or moral causality, whether it is a physical power or only a moral one; wherefore consult the dogmatic theologians.
