Chapter 9.—12. Likewise Honoratus of Tucca 1278 said: "Since Christ is the Truth, we ought to follow truth rather than custom." 1279 By all these declarations it is proved that we are not excluded from the communion of the Church, till it shall have been clearly shown what is the nature of the truth, which they say must be preferred to our custom. But if the truth has made it clear that the very regulation ought to be maintained which the said custom had prescribed, then it is evident both that this custom was not established or confirmed in vain, and also that, in consequence of the discussions in question, the most wholesome observance of so great a sacrament, which could never, indeed, have been changed in the Catholic Church, was even more watchfully guarded with the most scrupulous caution, when it had received the further corroboration of Councils.
