“In that Scripture proceeded from the Tradition that preceded it, and that both share the same author, it cannot be in a different or higher class than its antecedent.”
The problem is defining what one means by “Tradition” and how Scripture came to be established as being Divine.
Tradition as the oral form of Scripture before it was written would not be in a different or higher class in essence, but as the supernaturally established Word of God existing in a material expression it judges other claimed revelation.
Besides the fact that only part of Scripture first existed orally, tradition as an oral form of revelation in addition to the Scriptures, is amorphous, existing in a form along with uninspired revelation, without a known end or defined canon, and is supremely susceptible to undetectable corruption, while Scripture is the part of oral tradition that has been established as the Word of God, versus “tares’ which come from the same ground as wheat.
The Church and its Magisterium is a servant of the deposit of faith, not its creator or master.
Not in reality, as making her Tradition (out of the larger field of oral tradition) equal to Scripture is based upon Rome infallibly defining what the deposit of faith consists of and means, both in what revelation is of God and its meaning, thus infallibly defining that she is the assuredly infallible OTC.
Concerning which see my other recent posts relative to this.
From the Catechism of the Catholic Church:
80 The Tradition here in question comes from the apostles and hands on what they received from Jesus' teaching and example and what they learned from the Holy Spirit. The first generation of Christians did not yet have a written New Testament, and the New Testament itself demonstrates the process of living Tradition.
Tradition is to be distinguished from the various theological, disciplinary, liturgical or devotional traditions, born in the local churches over time. These are the particular forms, adapted to different places and times, in which the great Tradition is expressed. In the light of Tradition, these traditions can be retained, modified or even abandoned under the guidance of the Church's Magisterium.
105 God is the author of Sacred Scripture. "The divinely revealed realities, which are contained and presented in the text of Sacred Scripture, have been written down under the inspiration of the Holy Spirit."
"For Holy Mother Church, relying on the faith of the apostolic age, accepts as sacred and canonical the books of the Old and the New Testaments, whole and entire, with all their parts, on the grounds that, written under the inspiration of the Holy Spirit, they have God as their author, and have been handed on as such to the Church herself."
Peace be with you
But what do I do with a tradition like that which says Mary's childhood home was transported by angels from the Holy Land to Europe, landing a couple of times on the way?
And what of a tradition like the bodily assumption of Mary into heaven? Is there an inspired source that support such?
Who can I turn to to verify and put it on an equal footing with the written word?
But what the oral traditions that the disciples shared before any of the N.T. began to be set down in writing?
Even these are secondary to the written word as they became part of it and we have no preservation of those oral traditions as apart from or as a portion of inspired teachings.
