Or *I follow the pope.* or *I follow the Eastern Orthodox church.* or *I follow the Roman Catholic church*.
Nobody I know who's not Catholic follows Luther or any man. If they do, they're in a cult.
They follow Jesus, the Author and Perfecter of our faith.
But they don't belong to the Church he established.
“And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.” Mat 6:18
“I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.” John 16:12-13
“But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and foundation of the truth.” 1Tim 3:15
Then Jesus came to them and said, "All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age." Mat 28:18-20
Fortunately, we have Christ’s promise that heresies will never prevail against the Church. They will arise, endure sometimes for centuries, like Protestantism, but we can be confident in Christ’s promise that the Church He established will always teach the Truth.
