“This was precisely the pride of the Church in another ages: that from one end of the earth to the other, the brothers and sisters who came from each particular Church, provided with small tokens of identity for the journey, could find fathers and brothers everywhere. Unfortunately, the enemy of the Churches of Christ has robbed us of this privilege, along with everything else. We have each of us looks at each other coldly. (cf. Mt 24:12). However, Our Lord told us that only in this way would it be known who his disciples were: “in the love they have for one another” (cf. Jn 13:35).”
