Jesus gave his Church authority. Those who reject his church are to be treated as pagans. I would think this question should be considered closely by all who want to follow Jesus.
Which Church could this be?
Matthew 18
17If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, treat him as you would a pagan or a tax collector.
Luke 10
16"He who listens to you listens to me; he who rejects you rejects me; but he who rejects me rejects him who sent me."
John 20
21Again Jesus said, "Peace be with you! As the Father has sent me, I am sending you." 22And with that he breathed on them and said, "Receive the Holy Spirit. 23If you forgive anyone his sins, they are forgiven; if you do not forgive them, they are not forgiven."
1 Timothy 3
15if I am delayed, you will know how people ought to conduct themselves in God's household, which is the church of the living God, the pillar and foundation of the truth.
2 Thes 2
15So then, brothers, stand firm and hold to the teachings we passed on to you, whether by word of mouth or by letter.
Matthew 16
17Jesus replied, "Blessed are you, Simon son of Jonah, for this was not revealed to you by man, but by my Father in heaven. 18And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. 19I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven." 20Then he warned his disciples not to tell anyone that he was the Christ.
