Gresham Machen on Roman Catholicism

I think I agree with this from Gresham Machen (an arch Reformed Conservative Evangelical bastion of orthodoxy if ever there was one) about Romanism and Christianity:

Far more serious still is the division between the Church of Rome and evangelical Protestantism in all its forms. Yet how great is the common heritage which unites the Roman Catholic Church, with its maintenance of the authority of Holy Scripture and with its acceptance of the great early creeds, to devout Protestants today! We would not indeed obscure the difference which divides us from Rome. The gulf is indeed profound. But profound as it is, it seems almost trifling compared to the abyss which stands between us and many ministers of our own Church. The Church of Rome may represent a perversion of the Christian religion; but naturalistic liberalism is not Christianity at all.

(from Christianity and Liberalism, available free on line, towards the end of ch 2 on doctrine, HT: WB, JC, LG).

Whether or not the Roman Catholic church is a Church / teaches Christianity is of course debatable. I am inclined to think it might be a perverted church since while it has seriously corrupted the Gospel it does confess that Jesus Christ is Lord and Saviour etc.
