Remigius of Auxerre
Catena Aurea · Matthäusevangelium 5
And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell. And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
The reason why the right eye and the right hand are to be cast away is subjoined in that, For it is better, &c.
