Bede — on Rev 3:12 (Commentary on Revelation)

“He who overcomes, I will make him a pillar in the temple of my God, etc. He who overcomes adversities for my sake will gloriously fear no further loss of adversity in the temple of the Church. These pillars, that is, holy men, now strengthen the Church by supporting it, then will adorn it by standing out, just as those two in the doors of Solomon's temple.”
