ni8-shadow, I apologise on behalf of the others who feel it amusing or appropriate to chastise others looking to learn about their faith. I honestly find it very challenging to not slam them for slamming you, but that would be rediculous wouldn’t it.
But getting to you question on the Mosaic Law. I’m not the magisterium. I’m not even a Catholic with a degree in any sort of theology, but one way that I’ve heard scripture explained makes alot of sense.
When one teaches math to a child they don’t start with calculus or trig. They start with counting 1 to 10. Then they add 2 plus 2. Eventually it’s multiplication and division. Then we throw in variables, exponents, etc… and eventually they can do the calculus. But all this is very complex and must be learned piece by piece.
Similarly, God continues to reveal his truth. From Abraham, to Issac, thru Moses, thru King David, Jesus…and even more so today with different councils, saints, and apparitions.
First it was, the basics “trust and obey God” taught to Abraham by needing to offer Issac.
Later it was leaning His 10 commandments with Moses.
Learning God’s might and his gentleness thru King David’s battles and psalms.
Knowing God’s ultimate love through Jesus.
His changing grace though Pentacost.
Learning the trinity through church fathers.
Mary’s role through church councils and apparitions…etc…
But just as calculus doesn’t controdict addition. Today’s Cathoicism shoudn’t contradict the early faith. It can clarify it. But God’s actions then if right, are still right in today’s world. His truth isn’t relative.
But there are complexities. Like in math, that whole thing with
1/3 = .3333E
.3333E x .33333E = .99999E
1/3 x 1/3 = 1.
.9999E = 1 ?
People who know more than me can say this isn’t problematic. I look at it and think…huh? With enough knowledge the present teaching shouldn’t contradict the old teaching, though some may be context specific.
