Please explain.
You know Christians base our faith on the Word of God. Not the traditions of men.
You know there is no place in the Bible that identifies an office of Pope, nor suggests a smoke-signal method of choosing new ones.
And you further know your “Please explain” remarks indicate a shocking lack of Biblical and religous understanding on your part.
Read the Gospels. Read Acts, Romans and the letters to the churches. Disregard man-made doctrines that are not found in Scripture (like smoke-signals) and you’ll soon easily see the pathway to becoming a Christian.
