150 THE HISTORY OF HERESIES,
ciples, for he would be produced by
two Persons. We have
already answered this in proving the dogma (N. 6), but we will
explain it more clearly. Although the Father and the Son are
two Persons, really distinct, still they neither are, nor can be,
called two principles of the Holy Ghost, but only one principle,
for the power by which the Holy Ghost is produced is but one
alone, and is the same in the Father as in the Son. Neither is
the Father the principle of the Holy Ghost by Paternity, nor the
Son by Filiation, so that they might be two principles ;
but the
Father and the Son are the principle of the Holy Ghost by
active spiration, which, as it is one alone, and is common to both,
and undivided in the Father and the Son, therefore the Father
and the Son cannot be called two principles, or two spirators,
because they are but one spirator of the Holy Ghost, and
although both Persons spirate, still the spiration is but one. All
this has been expressly laid down in the Definition of the Council
of Florence.
REFUTATION V.
REFUTATION OF THE HERESY OF PELAGIUS.
1. It is not my intention here to refute all the errors of
Pelagius concerning Original Sin and Free Will, but only those
concerning Grace. In the historical part of the work (Chap, v,
art. ii, n. 5), I have said that the principal heresy of Pelagius
was, that he denied the necessity of Grace to avoid evil, or to do
good, and I there mentioned the various subterfuges he had re
course to, to avoid the brand of heresy, at one time saying that
Grace and Free Will itself was given us by God ; again,
that it is
the law teaching us how to live ; now, that it is the good example
of Jesus Christ ; now, that it is the pardon of sins ; again,
that it
is an internal illustration, but on the part of the intellect alone,
m knowing good and evil, though Julian, his disciple, admitted
