Yet, you cannot serve two masters.
You must choose to follow only Jesus Christ.
If you do so, you have chosen to have fellowship with Christ.
You are then directly and only accountable to Christ, and are to be lead by the Holy Spirit.
If you choose to follow Christ and only follow Him, how can a church have any authority over you?
You will then have authority under Christ, who is your master.
True leaders and disciples of Christ know they are equal with everyone else. They are not above others. They lead others on the way of truth, to Christ. They are servants. True leaders and disciples have humility. "And Gideon said unto them, I will not rule over you, neither shall my son rule over you: the Lord shall rule over you." (Judges 8:23)
Leaders of false churches will tell you that the church is the body of Christ. The truth is that the body of Christ are those who come to know Him. The body of Christ is composed of those who obey His words and commands, and serve Him. If we wish to be a member of the body of Christ, we must leave the ways of false churches and the world (pursuing lusts of the flesh, endless entertainment, opulent luxuries, selfishness, ego, pride, etc). The assembly of God is not an earthly church. Membership in an earthly church and following church leaders are not the way to heaven. You are not saved because you have a church membership and you go to a church. Dependency on church leaders leads many true believers in Christ astray because they get entangled in false doctrines and practices that actually pull them away from Christ.
We must be lead by Christ's spirit, and have a real and living relationship with Him where He knows you. Do not let leaders of false churches rule over you and deceive you. The only way of salvation is to follow Jesus as His disciple, having repented by turning to Christ and separating yourself from all ungodliness and evil, been baptized, and then continue to pursue the light and truth that God has imparted to you. Christ frees us from sin if we repent and do these things. Christ commands us to live a clean and pure life. Seek fellowship with Jesus Christ. Seek to know Him, to abide in Him, and to follow Him. Then, assemble yourself with other people who are striving to be disciples of Christ and have also taken the Holy Spirit as their guide (D&C 45:57).
Then, you will be serving the true Master who is Jesus Christ instead of one of a multitude of false masters who will enslave you.
