Actually, Scripture and Tradition are two separate sources of truth. The Church teaches that we don't believe Scripture because of the Church but that Scripture stands alone as one of two fonts of revelation. Revelation means to reveal. By it God reveals to man what he needs for salvation. That means Scripture is a necessary source for learning what God wants us to know, as is Tradition. Now, how can a person believe truly in a source of revelation if they are so prejudiced against scripture for being too cryptic to ever understand it? How beautifully the Galileo pagan assault has affected Catholics today; evidenced by the answers of people in this forum that deny the veracity of Scripture because it doesn't mean what it says.
Yes, separate but connected. Our Catholic Faith is based on Scripture and Tradition - at least that's what I've always been taught by traditional priests.
If faith and science are connected, as Jayne has admitted, then Scripture can't be left out, since it is one of the two pillars of our faith.
As you have described, St. Jerome, Origen, St. Augustine, and others believed that they could explain what the firmament meant. Indeed, the Galileo pagan assault has affected Catholics today, in that they deny the veracity of scripture.
