The soul, which is spirit, can not dwell in dust; it is carried along to dwell in the blood.
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 AugustineHear, O God. Alas, for man's sin! So saith man, and Thou pitiest him; for Thou madest him, but sin is in him Thou madest not. Who remindeth me of the sins of my infancy? for in Thy sight none is pure from sin, not even the infant whose life is but a day upon the earth.
Saint Augustine
