“But as it is now our purpose to discourse of the visible Church, let us learn, from her single title of Mother, how useful, nay, how necessary the knowledge of her
is, since there is no other means of entering into life unless she conceive us in the
womb and give us birth, unless she nourish us at her breasts, and, in short, keep us
under her charge and government, until, divested of mortal flesh, we become like the
angels (Mt. 22:30). For our weakness does not permit us to leave the school until we
have spent our whole lives as scholars. Moreover, beyond the pale of the Church no
forgiveness of sins, no salvation, can be hoped for, as Isaiah and Joel testify (Isa.
37:32; Joel 2:32).… By these words the paternal favour of God and the special
evidence of spiritual life are confined to his peculiar people, and hence the
abandonment of the Church is always fatal. [4.1.4]”
