Gregory the Great
Catena Aurea · Matthäusevangelium 11
Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: notwithstanding he that is least in the kingdom of heaven is greater than he. And from the days of John the Baptist until now the kingdom of heaven suffereth violence, and the violent take it by force. For all the prophets and the law prophesied until John. And if ye will receive it, this is Elias, which was for to come. He that hath ears to ear, let him hear.
(Hom. in Ev. xx. 14.) By the kingdom of heaven is meant the heavenly throne, whither when sinners defiled with any evil deed return in penitence, and amend themselves, they enter as sinners into the place of another, and take by violence the kingdom of heaven.
