Jerome
Catena Aurea · Matthäusevangelium 11
And as they departed, Jesus began to say unto the multitudes concerning John, What went ye out into the wilderness to see? A reed shaken with the wind? But what went ye out for to see? A man clothed in soft raiment? behold, they that wear soft clothing are in kings’ houses. But what went ye out for to see? A prophet? yea, I say unto you, and more than a prophet. For this is he, of whom it is written, Behold, I send my messenger before thy face, which shall prepare thy way before thee.
To add to this great worthiness of John, He brings a passage from Malachias, in which he is spoken of as an Angel. (Mal. 3:1)) We must suppose that John is here called an Angel, not as partaking the Angelic nature, but from the dignity of his office as a forerunner of the Lord.
