There is a slight refinement amid the usual ESP, though. It is the claim that our actions by themselves are worship, even though that is not our intent. Unfortunately that seems to be enough to condemn us.
Sadly for the author's argument, however, that is not how Elijah addressed Naaman.
And Naaman said: As thou wilt: but I beseech thee, grant to me, thy servant, to take from hence two mules' burden of earth: for thy servant will not henceforth offer holocaust, or victim, to other gods, but to the Lord. But there is only this, for which thou shalt entreat the Lord for thy servant; when my master goeth into the temple of Remmon, to worship there, and he leaneth on my hand: if I bow down in the temple of Remmon, when he boweth down in the same place, that the Lord pardon me, thy servant, for this thing. And he said to him: Go in peace.[2 Kings 5:17-19]
In this case, Naaman says in advance, "I intend to worship the LORD and only the LORD for the rest of my life. But when I go to this idol's temple with my king, and he kneels and expects me to do the same, I'm going to have to do it. Please pray for me, because I am not worshiping the idol at all."
And Elijah blesses him: "Go in peace."
So Naaman is going to bow down before an acknowledged idol, but has no intention of worshiping that idol. And Elijah blessed him: the prophet knew that this man had no intention of worshiping the idol, even though his external actions would seem to be those of an "idolater."
It's unambiguously obvious that intentions matter. Even if an action is done in an idol's temple, and even if it's an action that is normally a part of the worship of that idol - even then, an action is not intrinsically an act of worship. Period. Full stop.
But we Catholics are (so say the anti-Catholics) guilty of "worshiping Mary," even though we don't intend to do so and even though we're not even kneeling before an idol, and even though we're not in an idol's temple.
It must be great to be a mindreader. If you can actually do it, anyway.
Meantime, we Catholics don't worship Mary - no matter what Joe Anti-Catholic says.
Bonus problem: Naaman wants dirt from Israel. Why? He says he has no plans to offer sacrifice to false gods anymore. The implication is that the dirt is related to his plan to offer sacrifice only to the true God - i.e., that he plans to build an altar using it.
So here's a man who intends to do what is explicitly forbidden by God (building an altar other than the one in Jerusalem or the Tabernacle) for making offerings to God...and he is blessed by God's prophet.
But Catholics, who have no intention of worshiping the Saints, are supposedly guilty. Um...No.
