Your blatant satanic LIE does not make it true: the SPIRITUAL CHURCH OF JESUS CHRIST not the Catholic ORG began on that day when Peter preached. Conflating your ORG with the actual Body of Christ is but one of the big lies at the heart of your ‘other religion’, which is not Christianity.
Jesus inaugurated the church on Pentecost. The Catholic/Orthodox/Oriental Orthodox/Assyrian churches are that church, not your modernist interpretations like Mormons, Adventists, Pre-tribulation rapturists, Christian Scientists, Jehovah's witnesses etc
