Thomas Aquinas Quote from Summa Contra Gentiles

"Now such a wondrous conversion of the world to the Christian faith is a most
indubitable proof that such signs did take place....For it would be the most
wondrous sign of all if without any wondrous signs the world were persuaded by
simple and lowly men to believe things so arduous, to accomplish things so
difficult, and to hope for things so sublime".

Thomas Aquinas
