It is my understanding that Sacraments give us graces instituted by Christ. I saw a note that the Eucharist was the greatest Sacrament. I was wondering why it would not be Marriage? (as we are acting in his likeness?) (or even Holy Orders) The only thing I can see that would make this not correct would be that all people are not called to this Sacrament. I further do not understand how grace is measurable…greatest to least? Can you help me understand this in an easier manner? Thanks for all you do!
