Among other things, the Protestant Wettstein argued that variant readings “can have no weakening effect on the trustworthiness or integrity of the Scriptures.” The reason: God has “bestowed this book once and for all on the world as an instrument for the perfection of human character. It contains all that is necessary to salvation both for belief and conduct.” Thus, variant readings may affect minor points in scripture, but the basic message remains intact no matter which readings one notices.
I would guess this is the belief of many of the Southern Baptist believers I encountered in childhood. Many were devoutly committed to their personal relationship with Christ, but mostly uninterested in Christian lore and Church tradition.
