As a non-Christian, I hasten to plead guilty to this accusation. Jones cannot say, on pain of appealing to the very criterion he rejects, that I could trust my own mind to tell me that it is a true revelation. Surely we are on the road to an infinite regress. The upshot is that nobody, not even Jones, has any choice in the matter. We must trust our own minds about what is true, even if there is revealed truth.
Purported revelations are a dime a dozen.
The only possible answer is that our minds tell us that the Christian revelation is true and the Aztec one not. Hence, epistemological autonomy must be exercised to discover the true revelation, if there be any. In the main part of his article, Jones pillories Paul Kurtz, holding up Kurtz's book, The Transcendental Temptation, as exhibit number one in his prosecution of the case against non-Christian thought. Jones claims to perceive a tension in Kurtz's thought. Epistemological standards change and we cannot ever say that human beliefs represent an absolutely correct picture of reality.
