Bede the Venerable — as excerpted in the Catena Aurea on John 3:27-30

“He rejoiceth at hearing the Bridegroom’s voice, who knows that he should not rejoice in his own wisdom, but in the wisdom which God giveth him. Whoever in his good works seeketh not his own glory, or praise, or earthly gain, but hath his affections set on heavenly things; this man is the friend of the Bridegroom.”
