Catholic Tradition. Come what may

But we cannot understand any of this if we do not know exactly what the expression “the righteousness of God” means. There is a danger that people can hear about the righteousness of God but not understand its meaning, so instead of being encouraged they are frightened. St. Augustine had already clearly explained its meaning centuries ago: “The ‘righteousness of God’ is that by which we are made righteous, just as ‘the salvation of God’ [see Ps 3:8] means the salvation by which he saves us.”[2] In other words, the righteousness of God is that by which God makes those who believe in his Son Jesus acceptable to him. It does not enact justice but makes people just

Luther deserves the credit for bringing this truth back when its meaning had been lost over the centuries, at least in Christian preaching, and it is this above all for which Christianity is indebted to the Reformation, whose fifth centenary occurs next year. The reformer later wrote that when he discovered this, “I felt that I was altogether born again and had entered paradise itself through open gates.”[3]

Luther had Catholic ideas about Justification?

This is simply an insane assertion but that is what Ecumenism has wrought; rot.

More often than not, to be a Catholic is to be unaccompanied by the Magisterium; that is, I feel as though I am working alone just like The Killer was working alone, unaccompanied, in performing this song:
