What the young man in the video is presenting is a simplistic and radical form of evangelicalism whose intellectual roots are in the thought of Martin Luther. Luther famously held that justification (or salvation) takes place through grace alone accepted in faith, and not from good works of any kind.
To rely on liturgy or sacraments or moral effort for salvation, Luther thought, amounted to a pathetic “works righteousness,” which he sharply contrasted to the “alien righteousness” that comes, not from us, but from Christ. This basic theological perspective led Luther (at least in some texts) to demonize many elements of ecclesial life as distractions from the grace offered through Jesus, and this is why we find, even to this day in many evangelical Protestant churches, a muting of the liturgical, the sacramental, the institutional, etc.
These things constitute the “religion” that many evangelicals are against. And what the young man in the video learned from his evangelical teachers is that Jesus himself stood against these same “religious” distractions in his own day—which is why the Lord criticized the Pharisees for their fussy legalism and why he promised to tear down the Temple in Jerusalem.
Now Luther’s theological theory had enormous implications culturally and politically as well. The freedom that Luther declared from church law and institution soon morphed in the minds of many into a call for freedom from what were taken to be repressive political laws, traditions and institutions. One of Luther’s earliest and most provocative texts was titled "The Freedom of a Christian" and it is no accident whatsoever that “freedom” became the most powerful and explosive word in the modern political lexicon.
Indeed, our own country, which proudly bears the title “the land of the free,” was born in a great act of revolutionary anti-institutionalism—which goes a long way toward explaining why this young man’s video is getting such great play in America.
Well what does a Catholic make of all of this? Not much, as it turns out.
