The question at hand was holiness, and how to define it. Jesus gives us a correct understanding of holiness in the Sermon on the Mount, and in many other places in the Gospels.
A reverent atmosphere for worship is laudable, excellent even, but it does not define our holiness in God’s eyes. Worship does not make us righteous.
We owe God worship because of who He is and who we are - God is the creator and we are the creatures whom he has created. We owe God worship, and when we worship in a reverent way, we give God what we owe him. But if worshipping God is all we do, no matter how much reverence we hold in our heart or in our actions, if all we do is worship at Mass, then all we have given to God is the absolute minimum owed to him, that which is his in the first place by right, and we are like the unprofitable servant who buried his master’s money. .
Mass is just the beginning. Worship is our minimum obligation. The word Mass means “to send forth”. Those are the last words of the Mass. Ite, missa est. Go forth or be sent. We are supposed to bear fruit in love.
Jesus corrects the Pharisees understanding of holiness as how you worship God, and tells them that if they treat people like garbage then their worship is an abomination to God. We are supposed to bear fruit, and it is not the worship that makes us holy, but how we treat each other.
That was the question; what makes us holy. Worship does not make us holy.
