Contend not in words

Of these things put them in mind
charging them before the Lord.

Contend not in words:
for it is to no profit,
but to the subverting of the hearers.

haec commone testificans
coram Domino

noli verbis contendere
in nihil utile
ad subversionem audientium

(2 Timothy 2:14 - from today's first reading)
