All these effects are not necessarily inherent in any one blessing; some are caused by one formula, and others by another, nor are they infallibly produced. It depends altogether on the Church's suffrages that persons using the things blessed derive supernatural advantages. There is no reason to limit the miraculous interference of God to the early ages of the Church's history, and the Church never accepts these wonderful occurrences unless the evidence in support of their authenticity is absolutely unimpeachable.
