"What does the Church mean when she says that the Sacrament of Marriage confers special sacramental graces on those who receive it?"

The graces of the Sacrament of Marriage help the couple face challenging issues that arise after marriage. Every married couple faces unique problems, which can include communication problems between themselves, sacrifices that arise with troubled children, health issues of a spouse, or temptations to infidelity. When two baptized Christians validly marry, they receive graces gained by Jesus on the cross that remain with them through life and offer them as a couple the special helps that they need during their marriage. Married couples can be confident that they will receive these graces and are encouraged to pray for them.
