Is the Sacrament of Matrimony a Sacramental Grace?

Marriage is by its very nature, a sacrament. It's not possible for two baptized people to be in a real marriage without it being a sacrament. So because they minister the contract and the bonds to each other, that bond becomes elevated as a means of grace. They are in that sense ministers of God to each other. The husband and wife enter into something by their own free act, which will be the cause of further graces to the other party.
