Vos estis sal terr. Quod si sal evanuerit, in quo salietur ? ad nihilum valet ultra, nisi ut mittatur foras, et conculcetur ab hominibus. Vos estis lux mundi. Non potest civitas abscondi supra montem posita, neque accedunt lucernam, et ponunt eam sub modio, sed super candelabrum, ut luceat omnibus qui in domo sunt. Sic luceat lux vestra coram hominibus : ut videant opera vestra bona, et glorificent Patrem vestrum, qui in clis est.

ENG:

You are the salt of the earth, but if the salt has lost its flavor, what will it be salted with? It is then good for nothing, but to be cast out and trodden under the feet of men. You are the light of the world. A city set on a hill can't be hid. Neither do you light a lamp, and put it under a bushel basket, but on a stand; and it shines to all who are in the house. Even so, let your light shine before men; that they may see your good works, and glorify your Father who is in heaven.
