Just following His words.
“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
"Truly I tell you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.” Mat 18:18
“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
You follow your church and their teachings. That is all. The gates of hell prevailed against Peter. He denied his Lord three times. These verses have meanings which do not confirm your denial of the life Christ. Jesus was a Jew. He lived as a Jew. He followed Jewish laws including the Sabbath. Do what you will.
