Two Masters

Nemo potest duobus dominis servire, etc Duum dominorum infidele servitium est, nec par ejusdem potest esse ad saeculum atque ad Deum cura. In alterum enim necesse est odium sit, in alterum amor: quia idem opus diversae dominorum non conveniat voluntati, nec pauperes spiritu Deo placentes ambitiosae saeculi hujus possint apti esse jactatiae. Sanctus Hilarius Pictaviensis, In Evangelium Matthaei Commentarius, Cap V Source: Migne PL 9.944b

No one is able to serve two masters... 1 Servitude to two masters is unfaithfulness; one cannot have equal care for the world and God. It is necessary that one must hate one and love the other, because the same work does not suit the differing wishes of the masters. It is not possible that the poor in spirit, 2 who are pleasing to God, are suitable for the pleasing of this vain world. Saint Hilary of Poitiers, Commentary on the Gospel of Saint Matthew, Chapter 5 1 Mt 6.24 2 Mt 5.3
