Symmachus, Dispatches 3.10
aequum est, quidquid omnes colunt unum putari. eadem spectamus astra, commune caelum est, idem nos mundus involvit. quid interest, qua quisque prudentia verum requirat?
It is equitable that whatever everyone worships should be considered to be one. We look at the same stars, the sky is shared, the same world envelops us. What difference does it make by what wisdom each person seeks out the truth?
