If was the Catholic Church which early departed from the doctrines of Christ, and thus forfeited the claim to be the true Church.

If you think that, by departing from the truth, the Catholic Church forfeited the claim to be the true Church, then you believe that the infallible retention of the teachings of Christ must be a mark of the true Church. Is your own Church, therefore, infallible? Does it even claim to be so? I admit that if the Catholic Church has failed in witnessing to the truth she is not true, and I would at once leave her. But as this would mean that Christ was unable to keep His promise, I would also abandon belief in Christ. Certainly, wherever else I might go, I would not return to a Protestant Church based upon the doctrine that Christ has failed to keep His promise.
