Today religious leaders from all branches of Christianity accomplish good things while teaching apostasy. The apostles said that apostasy would be ripe after he and the others died, and is how we are refined by testing the apostasy against the bible to know our God. This is seen in the letters to the 7 congregations in revelation. Today, christians are the same as the parisees in Jesus day when he told them;
Matthew 15:7 "You hypocrites, Isaiah aptly prophesied about you when he said:8 ‘This people honor me with their lips, but their hearts are far removed from me.9 It is in vain that they keep worshipping me, for they teach commands of men as doctrines.’”
Christians in first century so quickly started to act like Pharisees and revere people like Paul or Apollos, creating sects and teach commands of men, instead of Jesus who died. Paul rebuked them for this and was glad he was not the one who baptized them.
.
This is why you need to pray for humility and understanding so you can understand God's word through man's apostasy which are commands of men as doctrine. The congregation is there, imperfect run by men and full of apostasy, so keep your garments clean. Revelation 3:4
