The Devil often transforms himself into an angel to tempt men, some for their instruction, some for their ruin.
Saint AugustineAs to the fable that there are Antipodes, that is to say, men on the opposite side of the earth where the sun rises when it sets to us, men who walk with their feet opposite ours, that is on no ground credible. Even if some unknown landmass is there, and not just ocean, there was only one pair of original ancestors, and it is inconceivable that such distant regions should have been peopled by Adam's descendants.
Saint AugustineBaptism does not profit a man outside unity with the Church ... For many heretics also possess this Sacrament but not the fruits of salvation ... The benefits which flow from Baptism are necessarily fruits which belong to the true Church alone. Children Baptized in other communions cease to be members of the Church when, after reaching the age of reason, they make formal profession of heresy, as, for example, by receiving communion in a non-Catholic Church.
Saint AugustineIf a parricide is more wicked than anyone who commits homicide-because he kills not merely a man but a near relative-without doubt worse still is he who kills himself, because there is none nearer to a man than himself.
Saint Augustine
