Notice that the above quote [your accusatory words] includes "Faith Alone", Sola Fide. (One of the five Solas, which stand together.) You included Sola Fide in a list of "inventions".
Yet in this post I am responding to, you said;
There goes the "invention" claim, in regards to Sola Fide, for you've contradicted yourself.
The Sola Scriptura (again, but one Sola of five which need be regarded together) can be found in Scripture itself, and in the teachings (tradition as it were) of the Early Fathers.
I'm going to be generous, and assume here for sake of discussion that although you listed Sola Fide as an "invention", it does not mean that the RCC borrowed the idea from the Reformers. [smile]
Yet for the sake of discussion, they did indeed help bring much focus upon it, during those turbulent times.
As far as the Sola Scripturas is concerned, the opposition to it is based upon the desire & premise of replacing it with Sola Ecclesia (Whatever We Say). That much is plain enough.
See "The Catechism of the Catholic Church", page47, paragraph 153, entitled, Faith is a Grace.
While someone might make a reasonable case that "Grace Alone" is what the Catholic Church teaches, "Faith Alone" is most definitely not what the RCC teaches.
Faith comes through the Grace, is fostered in us by the Holy Spirit, and leads us to our Savior Jesus Christ. As we move closer to Christ and cooperate with the Holy Spirit, our faith deepens. Our cooperation with the Holy Spirit along with the additional Grace we receive through the Eucharist and other sacraments in turn increases our faith which draws us closer to Jesus Christ, in a cycle that draws us each as close to Christ as our cooperation with Grace will allow us to go, up to and including Sainthood for those with sufficient Faith and trust in Christ to totally surrender to Him.
So, like I said, someone could argue about whether or not "Grace Alone" is Catholic teaching but not "Faith Alone". Especially not "Faith Alone" as described by "sin boldly" Luther, those who deny the Trinity, those who defame The One, Holy, Catholic, and Apostolic Church Jesus Christ Himself established, and the vast majority of those who espouse Luther's "Faith Alone" heresy and it's close cousins derived from various Eastern cults rather than Scripture.
