I looked it over and some of the others that have been cited and they ALL have the same essential flaws. The most glaring of which being that they espouse Sola Scriptura, which IMO disqualifies almost everything else that they attempt to say.
If that errant doctrine were true then we’d all be in the same theological interpretative mess that the n-Cs are. That is the primary place to begin with the refutation of their comments. I disagree that that is the best presented site, since they borrow extensively from other sources and anyone who would believe the rhetoric of Mary Ann Collins (the supposed nun

) was predisposed to anti-Catholicism to begin with.
The only thing that I found refreshing was that there seems to be a bit less vitriol in their pages, but their positions are errant and factually inaccurate. History does not support the things that they allege.
For instance, Was the early church Catholic? ABSOLUTELY!
When the bishop of the church at Antioch, who was discipled by St. John the apostle himself writes. "CHAP. VII.–LET US STAND ALOOF FROM SUCH HERETICS.
They abstain from the Eucharist and from prayer,(7) because they confess not the Eucharist to be the flesh of our Saviour Jesus Christ, which suffered for our sins, and which the Father, of His goodness, raised up again. Those, therefore, who speak against this gift of God, incur death(11) in the midst of their disputes. But it were better for them to treat it with respect,(13) that they also might rise again. It is fitting, therefore, that ye should keep aloof from such persons, and not to speak of(15) them either in private or in public, but to give heed to the prophets, and above all, to the Gospel, in which the passion[of Christ] has been revealed to us, and the resurrection has been fully proved.(16) But avoid all divisions, as the beginning of evils." That tells you that they believed the Catholic teaching on the real presence. Anyone who rejects that is not in line with either the New Testament or the teachings of the early church.
When that same St. Ignatius of Antioch then writes. "CHAP. VIII.–LET NOTHING BE DONE WITHOUT THE BISHOP.
See that ye all follow the bishop, even as Christ Jesus does the Father, and the presbytery as ye would the apostles. Do ye also reverence the deacons, as those that carry out[through their office] the appointment of God. Let no man do anything connected with the Church without the bishop. Let that be deemed a proper(18) Eucharist, which is[administered] either by the bishop, or by one to whom he has entrusted it. Wherever the bishop shall appear, there let the multitude[of the people] also be; by the bishop, or by one to whom he has entrusted it. Wherever the bishop shall appear, there let the multitude[of the people] also be; even as, wherever Jesus Christ is, there is the Catholic Church." That tells you that the bishop of the church in the very city “where we were first called Christians” (Acts 11:26) shows that even at that time the church called itself “the Catholic Church”.
The “information super highway” sadly has many bad maps that lead to factually inaccurate side roads…especially where religion is concerned.
In conclusion “Calvary Chapel” is one of the most anti-Catholic bunches out there and the ones in my area, (less than 5 miles from my house, and people that I used to go to church with) are pretty "smiley, but they wouldn’t know an early church writing from a Chick tract.
Pax tecum,
