In illo témpore: Dixit Jesus discípulis suis: Nemo lucérnam accéndit, et in abscóndito ponit, neque sub módio: sed supra candelábrum, ut, qui ingrediúntur, lumen vídeant. Lucérna córporis tui est óculus tuus. Si óculus tuus fúerit simplex, totum corpus tuum lúcidum erit: si autem nequam fúerit, étiam corpus tuum tenebrósum erit. Vide ergo, ne lumen, quod in te est, ténebræ sint. Si ergo corpus tuum totum lúcidum fúerit, non habens áliquam partem tenebrárum, erit lúcidum totum, et sicut lucérna fulgóris illuminábit te.
At that time, Jesus said to His disciples, No one lights a lamp and puts it in a cellar or even under the measure, but upon the lamp-stand, that they who enter in may see the light. The lamp of your body is your eye. If your eye be sound, your whole body will be full of light. But if it be evil, your body also will be full of darkness. Take care, therefore, that the light that is in you is not darkness. If, then, your whole body is full of light, having no part in darkness, it will all be illumined, as when a bright lamp illumines you.
