Naturally without sin. The theology here is very intricate and
must be followed with the utmost caution. All have free-will, and therefore
might sin. But Our Lord and Our Lady did not sin; and the thought that they
might have sinned is blasphemy. And S. John says (I. iii. 9):
Whosoever is born of God, committeth not sin: for his seed abideth
in him, and he cannot sin, because he is born of God.
