Here’s a question I’ve been curious about, and it is one I’m still thinking through and would love some input from my Catholic brothers and sisters (protestant takes on it would be interesting too).
So, we have the Old Covenant which the Mosaic Law was a part of. At that time and under that Covenant there was a high priest, a separate priesthood, sacrifices that only covered sin for a short period of time, and the sacrifices needed to be repeated. There was one day set aside for specific reasons (Saturday) and everyone had to follow that. Faith was intimately connected to action; God says a thing, and the person trusts God and the result is action.
Then we have the New Covenant. From the RCC’s perspective there’s a high priest (Jesus) and a separate priesthood. There is an acknowledgment of the once and for all sacrifice of Christ, and that sacrifice is made present again and again through the mass. The sacraments only cover sin for a short period of time, and needs to be repeated. There is one day set aside for specific reasons (Sunday) and everyone had to follow that. Faith is intimately connected to action; God says a thing and the person trusts God and the result is action.
So, what from the Catholic perspective, was the need of a New Covenant? We’d all agree it is a better covenant, so what is the main difference in outcome for us on a daily, yearly, and lifetime basis?
