If it comes down to your interpretation of Scripture or the traditional interpretation of the Church — the Church that Christ founded, the church to which Jesus commands us to take our disputes, the church that Scripture calls “the pillar and foundation of truth,” well, I will choose the latter.
Acts 4:12 And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.”
Including the name of the Catholic church.
It's a person who saves and that person is Jesus and Him only.
