A noted commentator on liturgical law has mused that many of the abuses apparent in the celebration of the liturgy in some places may, indeed, be lawful custom. A custom can be described as a “common tradition” as opposed to an abuse, which is a “corruption.” A custom, while itself never becoming a law, obtains the force of law when certain ingredients are present. The Code of Canon Law acknowledges certain standards. The tradition emanates from the community of the faithful rather than a legislator although the custom must be approved by the latter (canon 23). Moreover, the community of the faithful must be capable of receiving a law, e.g., a diocese, a parish, a religious institute, a public association of the faithful, etc., (canon 25). The required approval may be express or tacit. If the custom is contrary to divine law it can not be enforced. Nor can a custom that is contrary to or beyond canon law be enforced unless it is a reasonable one. However, a custom that is expressly reprobated is not regarded as a reasonable one (canon 24). years. According to canon 26, “Unless the competent legislator has specifically approved it, a custom contrary to the canon law now in force or one beyond a canonical law (praeter legem canonicam) obtains the force of law only if it has been legitimately observed for thirty continuous and complete years. Only a centenary or immemorial custom, however, can prevail against a canonical law which contains a clause prohibiting future customs.”
