When I first came across this quote I thought it was overstated and simplistic, but the longer I think about it the more I think Ron Rolheiser is gesturing toward an important truth here. From “The Power of Praying a Doxology” in Northern Lights:
Spiritual writers have always told us that we are either growing or regressing, never neutral. This means that we are either praising someone or demanding we be praised, offering gratitude or muttering in bitterness, blessing or cursing, turning attention away from ourselves or demanding it be focused on us, expressing admiration or demanding it, praying a doxology or doing violence. We are always doing one or the other and it’s only by deflecting attention away from ourselves, which is what we do in essence when we give glory to God, that we save ourselves from egoism, jealousy, bitterness, greed, and violence…
The main reason our faith asks us to constantly render glory to God is that the more we praise the less we slander, gossip, or pass judgment. Offering praise to God, and others, is what saves us from bitterness and violence.
