Sacraments are instruments, they do what they signify.
Sanctifying grace increases.
Sacramental graces are made available (constantly), though they might not be able to be fruitful because of mortal sin or lack of attentiveness to receiving it fruitfully.

**Through the sacrament of marriage, Jesus' love for the Church is MADE present!
There are helping graces for the natural ends of marriage that have now been supernaturalized: procreation/education of children, and to be helpmates to each other.
The other category of helping graces is to help re-order marriage, family life, and the world towards divine ends. Marriage, therefore, becomes a remedy for sin, it builds up the Church, and is an element of the substance of our divine worship.

We get into some stuff here:

A Sacrament is a sacred sign instituted by Christ to sanctify us and build up the Church.

It is a primordial sacrament from the beginning because it is a communion of persons that represents THE Communion of Persons, and because it foreshadows the love of Christ for His Church

The administrators are the couple themselves that exchange vows.

The sign is the consent of the couple, and the enduring part of the sacrament is the marriage bond.

This is awesome. This is an excellent candidate for wedding readings any day of the week!
