In “The Faith of Our Fathers” Catholic Cardinal Gibbons wrote: “If only one instance could be given in which the Church ceased to teach a doctrine of faith which had been previously held, that single instance would be the death blow of her claim to infallibility” (p.74).
Here is what Acts 20:7a says about the frequency with which we should take communion: And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them.”
Notice the Catholics admit they have changed on this issue: In the beginning Mass was celebrated only once a week, then three or four times, and finally, in the fifth or sixth century, every day. (Legislation on the Sacraments in the New Code of Canon Law, p.87, Ayrinhac)
Remember, according to Cardinal Gibbons, change is the “death blow … to infallibility.”
