John Chrysostom
Catena Aurea · Matthäusevangelium 5
Blessed are the pure in heart: for they shall see God.
By the pure are here meant those who possess a perfect goodness, conscious to themselves of no evil thoughts, or again those who live in such temperance as is mostly necessary to seeing God according to that of St. Paul, Follow peace with all men, and holiness, without which no man shall see God. For as there are many merciful, yet unchaste, to shew that mercy alone is not enough, he adds this concerning purity.
