Mary, help of Christians/Preface
Preface
The contents of the following pages are based on the Catholic doctrine of the veneration and invocation of the saints, and of the efficacy of the prayer of intercession. The legends of the individual "Holy Helpers" were compiled from authors whose writings have the approval of the Church.
In compliance with the decrees of Pope Urban VIII of 1625, 1631, and 1634, the compiler formally declares that he submits everything contained in this little book to the infallible judgment of the Church, and that he claims no other than human credibility for the facts, legends, and miracles related, except where the Church has otherwise decided.
