szentségjel
A szentségjel, often translated as "sacramental sign" or "sacrament," refers to the outward and visible sign of an inward and spiritual grace instituted by Christ in the Roman Catholic, Orthodox, and some Protestant traditions. These signs are not merely symbolic but are understood to be efficacious, conveying the grace they signify. The efficacy of the sacrament is often attributed to the *ex opere operato* principle, meaning the sacrament is effective by virtue of the sacramental act itself, provided it is performed by a valid minister and with the intention of doing what the Church does.
