 As St. Paul says in Ephesians, one faith, one baptism, one God and Father of all. Although the church properly is the congregation of saints and true believers, nevertheless, since in this life many hypocrites and evil people are mingled therewith, it's lawful and permissible to use sacraments administered by evil men. According to the saying of Christ, the scribes and Pharisees sit in Moses' seat, Matthew 23.
