I have personally meet Ross at Oxford Univ, from his mouth, with his tongue he explained to me that he held to the Westminster confession as a solid position statement. He aligns himself with the Presbyterian PCA, which is the conservative arm of the denomination. It does NOT hold to tongues, and is anything but cultish. I suggest that you are thinking of someone else in this regard, as Ross holds to none of the word of faith doctrines, and his theology is based in the Westminster confession of Faith, and does not at all hold to tongues...that sounds like a pentacostal doctrine, and Ross does NOT fall into that catagory either.
You must have him confused with someone else.
