Seitz served as an adjunct professor at the University of Dallas from 1985 to 1994, teaching liturgy and sacramental theology.
He also painted the Sept Sacrements, or Seven Sacraments, in the choir of the Tournai cathedral in order to replace the superb tapestries stolen by the Jacobins during the revolution.
The other Last Rites are Confession (if the dying person is physically unable to confess, at least absolution, conditional on the existence of contrition, is given), and the Eucharist, which when administered to the dying is known as "Viaticum", a word whose original meaning in Latin was "provision for a journey".
While they are not ordained and thus do not celebrate the Sacraments, they serve in a variety of important apostolates according to the talents of each brother.
