I’m not trying to scare you into idolatry. All I’m saying is, read what the saints and the liturgy says. I’m Catholic and I worship God and God alone. But our liturgy is also an expression of our faith, so when we day “Come, let us adore” in response to “Behold the wood of the Cross”, we are invited to examine why. The Cross is so closely united to Christ and has become, as it were, an image of him. That’s why St. Thomas had no problem saying that we adore the Cross with latria because it is actually the latria to Christ himself.Maybe you do. I do not. And all of this is bringing me closer and closer to making a promise before God that I will neither worship nor venerate any person or thing, with the exception of God in His three Persons. If I am wrong, God can correct me; He knows where I live.
Did you even read that section of the Summa and can you really say that you can argue with his logic? He wasn’t the Magisterium, yes, and he wasn’t a Pope, yes. But the Church uses it in her liturgy: “We worship your Cross O Lord” (Sept. 14 Lauds) and the Liturgy is indeed part of the Magisterium because it is promulgated with her own authority. And the Church, being infallible and indefectible, will not promulgate anything blasphemous or idolatrous. I therefore always start with this principle: “The Church is right, now I need to understand.”
I’m insisting on St. Thomas because it shows how rich the Catholic faith is and how healthy its regard is for created matter. It shows that we can indeed worship God through the things of this world he has united to himself, so we do not worship God in a vaccuum but with the entirety of our senses.
