Out of the Catholic Church none can be saved. This proposition, which highly displeases all sectarians and infidels, is not only clearly established by the authority of Scripture, and by the perpetual and constant belief of the Catholic Church, but it is also evident from reason itself, so that one must needs be blind who does not perceive its truth. This, however, applies only to those persons who culpably and willfully adhere to heresy, or schism, or infidelity, but by no means to those who have been imbued with errors and prejudices from their earliest years, and to whom not even a doubt occurs that they are involved in heresy or schism, or who, if any doubt arises in their minds, earnestly and sincerely seek after the truth; such persons we leave to the judgment of God, to whom it belongs to penetrate and search the thoughts and dispositions of hearts. For it is incompatible with the divine goodness and clemency that any one should suffer eternal torments who is not guilty of a willful transgression. To assert the contrary would be against the express doctrine of the Church.
"Let us hear St. Augustine: We must not, says he, class among heretics those persons who, without willful obstinacy, maintain a false and perverse doctrine, especially if it is not the off-spring of their bold presumption, but a legacy from their deceived and mistaken parents, and who search after the truth with earnest care, being disposed to renounce their error as soon as they are apprised of it.
Reading this from Father Lasance's famous prayer book is a huge comfort whenever I worry about my Baptist relatives.
