Well you need to believe the true gospel which is salvation by grace through faith alone , it is not salvation by being water baptised in the right water temperature and you don't need to speak in tongues to be saved.
Also it's quite obvious you don't understand the Gospel, as per one of your last posts #41, you do not say the Father sent the Son to die for the sins of the whole world as per Christian belief but rather attribute the crucifixion to be a " flesh versus spirit" struggle.
While your Oneness Pentecostal's were still getting their act together around 1914 starting off only as a handful of like minded unbelievers.. the Nicene creed affirming the truth of the Trinity has been around since 325 AD.
