The fact remains the Roman Catholic is told be examine and follow his conscience while the Protestant is ridiculed for doing just that.

The rest of your comments about the OPC are nonsensical. Theonomy simple refers to "God's law." I understand how a church like the RCC which often breaks God's law is so unfamiliar with the term. From Wikipedia...

The term "Theonomy" has been used to describe various views which see the God revealed in the Bible as the sole source of human ethics. Using the word in this sense, Cornelius Van Til argued that there "is no alternative but that of theonomy or autonomy" (Christian Theistic Ethics p. 134).

You disagree with that?

If you're interested, here's the OPC's website.

Welllllllll . . . OF COURSE!

The DOCTRINE OF HOLY DUPLICITY makes available special dispensations for those clever enough to jump through all the convoluted tunnels and monkey bars to score points going and coming and all points inbetween.

The more impossible the paradoxes and duplicities, the more gilded white hankies one’s awarded for being a good clique member.

The fact remains that your question was wrong -- Annalex said "a Catholic is instructed to examine his conscience before presenting himself for Holy communion", to which you said "Interesting. So here the Roman Catholic is to trust his conscience, but the Protestant who believes in Jesus Christ is not to trust in or rely on his conscience. " ---> apples and oranges:

Annalex says about examining your concience prior to Holy communion and you ask a question about some trusting their conscience to follow the teachings of Machen like the OPC does and to make Machen some kind of demi-god if not God.
Why DO Machenites in the OPC believe that Baptists are wrong? And they also disagree with Branch Davidians on beliefs and Luherans and Arminians on episcopality or theology.

Finally, why does the OPC believe in Theonomy, that only the OPC should be allowed as state religion and others should receive capital punishment?

And you use WIKIPEDIA to argue OPC doctrines?
