6 In this matter the holy clergy should surpass in example all others. Indeed, it is at variance with their office to mingle in such dissensions. If they should reside in places inhabited by people of different races or languages, unless they abstain from any appearance of contention, they may easily incur hatred and dislike from both sides. Nothing could be more detrimental to the exercise of their sacred function than this. The faithful, to be sure, should recognize in fact and practice that the ministers of the Church are concerned only with the eternal affairs of souls and do not seek what is theirs, but only what is Christ's.
