The will of God…

Be resigned to the will of God in all things; make frequent acts of submission; regard with the eye of faith all interior and exterior troubles as coming from God; do not think of the future – that is, of its misfortunes, its trials, and other occurrences which the imagination may conjure up, but dispel them in the will of God.
–Saint Paul of the Cross (1694-1775)

Spare the faith…

Whosoever you are who introduce new doctrines, I beseech you to spare the ears of Romans! Spare that faith which was commended by the voice of an Apostle. Why should you attempt to teach us, at the end of hundreds of years, that which we never heard before? Why bring forward what Peter and Paul did not will to make known? Until this day, the world was Christian without your doctrine. Thus, I hold as an old man onto that faith wherein I was regenerated as a boy.
–Saint Jerome (c. 340-420)
