So that settles the argument then I hope. St Alphonsus Doctor Of The Church says BOD is de fide. Strangely I feel like there some who will not accept this.
St. Alphonsus Ligouri and ALL the Fathers, Doctors, and Saints, rejected salvation by implicit faith, that is the salvation of the Muslim, Jҽωs, Hindus, Buddhists, which I am certain is what you believe. So you reject the very saint that you bring forward.
