Oh, some of us hard-line unreconstructed right-wing conservative Calvinists do oppose the “holy days.” I regularly work hundred-hour weeks, six days per week but nothing on the Lord's Day, which is the only biblical day of rest.
But would I publicly campaign on Maundy Thursday or Good Friday if I were a candidate for office? Probably not. Considering that Rick Santorum is a conservative Roman Catholic, taking four days off from campaigning for Easter makes sense. I don't agree with Santorum’s Catholicism but I certainly do not oppose him practicing what he professes.
Just a point. Day of rest, yes, but not the only one that was celebrates/observed. Jesus professed this in practicing Judeism. The seventh day was set aside as just that a “day” of rest.
Glad to hear you don’t hold his Catholism against him.
Go Rick!
