Every Sacrament comprises, inter alia, matter and form. In the Eucharist, the matter is the subject of the consecration, viz. the bread and wine. In baptism, confirmation, and anointing, the matter is the instrumentality, be it water or oil. I’m puzzled about the matter for reconciliation, matrimony, and holy orders.
The intriguing suggestion was made here that the matter of Orders is, as in the eucharist, the subject (viz. a male who is able to receive the sacrament), and I suppose that by the same reasoning, the matter of the sacrament of matrimony is a man and a woman who are eligible to receive the sacrament. Does that seem correct, and if not, what is the correct matter for these two sacraments? I suppose that by analogy to baptism, confirmation, and anointing, the instrumentality of the imposition of hands could be considered the matter for Orders, but that leaves matrimony standing alone (and on a shallow scriptural foundation, I must confess).
Lastly, reconciliation. I’ve read non-magisterial sources that variously suggest the confession made or the penance imposed as the “matter,” but these seem to play fast and loose with the meaning of materia. So what is the matter in the sacrament of reconciliation?
