Papal fiat supercedes the Bible, because the Pope has been declared inerrant in the first Vatican Council of 1870. They declared the Pope speaks "ex cathedra" (i.e., "from his chair" or authoritatively), ergo he is infallible in matters of faith and morals.
However, the same catholic church teaches a position of "limited inerrancy": Scripture is inerrant, but not all of it.
Why were the inquisitions focused on heretics who believed in "sola-scriptura"? Because this doctrine threatens the popes authority.
The Papal edicts are meaningless in this debate, especially to a protestant.
You didn't bother actually reading what I posted, did you?
Okay. I'll try it another way. Have you seen this or this?
The first link is to a FR thread about the Bishop of Eastern Michigan, the Rt. Rev. Edwin M. Leidel, Jr., (the Episcopal Diocese of Eastern Michigan, that is), who has commended to the clergy of his diocese an internet petition that supports the teaching of evolution in public schools.
While this particular Bishop may be of no interest to you, he's been joined by the Rt. Rev. David Andres Alvarez-Velazquez, Bishop of Puerto Rico; the Rt. Rev. Joe Burnett, Bishop of Nebraska; the Rt. Rev. C. Christopher Epting, Presiding Bishop’s Deputy for Interfaith and Ecumenical Relations; the Rt. Rev. Leo Frade, Bishop of Southeast Florida; the Rt. Rev. Wendell N Gibbs, Jr., Bishop of Michigan; the Rt. Rev. Mark Hollingsworth, Jr., Bishop of Ohio; the Rt. Rev. James Kelsey, Bishop of Northern Michigan; the Rt. Rev. Rustin Kimsey, acting Bishop of Navajoland; the Rt. Rev. Robert Moody, Bishop of Oklahoma; the Rt. Rev. F. Neff Powell, Bishop of Southwestern Virginia; the Rt. Rev. Katharine Jefforts Schori, Bishop of Nevada; and the Rt. Rev. Keith Whitmore, Bishop of Eau Claire.
Just fyi.
