Brotherly love comes from the Greek word philadelphia which is a manifestation of love different from the other two types of love we find in the scriptures, love eros and agape love, fileo or filial love is that we feel for those who are part of of our natural family or that come to be as in the case of the believer who meets the family of God. This is a love that overcomes the barriers of idiosyncrasy, personality, tastes, culture, knowledge and position, when we love a brother, we feel him as part of us, we can be one with them and stay with them , we can learn, honor and serve them without being a burden, only those who love the brothers in the faith can teach, preach and act according to it. As beings in perfection we must practice with constancy all virtue and service, as the writer mentions about hospitality, because we do not know who we host and whom we serve. Trust in God must be absolute, there must be no doubt, because if it exists then despair, anxiety, laziness, and distrust in the mind will arise. of the man who will lead him to lose faith and with the id will stop acting.
