Bede — on Rev 6:6 (Commentary on Revelation)

“A measure of wheat for a denarius, etc. He says, Beware lest you scandalize your brother by a very bad example, for whom Christ died and who bears the marks of the sacred blood and chrism. For whether by the merits of the perfect, or even of the least, anyone in the Church imbued with faith in the Holy Trinity is redeemed at the same perfect price of the Lord's blood. And not without reason is the perfection of faith or work expressed by a double measure and not a single one, which both consist in the root of twin charity.”
