I think we agree on the word sacred. It is set apart and holy. The word infallible has come up in connection with sacred tradition saying that tradition is without error and that the Church is without error.
Perhaps this is a problem due to the disparate definitions of Church? For most of our separated brethren, “church” is the “body of believers on earth”. This is an inadequate definition compared to what received from the Apostles, who taught the Church is One and Holy. But it is not the “body of believers on earth” that make her Holy and infallible, it is the divine elements.
The gift of infallibility is a “negative” gift, meaning it is preventative. By it the Church is prevented from teaching error. If the Church taught error, the faithful would go astray, and pass through the gates of hell. Since Jesus promised that the gates of hell would not prevail, He prevents the Church from teaching error.
This does not mean that individuals are infallible, or that everything taught or done by members of the Church is infallible. It means that the once for all divine deposit of faith is preserved infallibly by the Holy Spirit.
The 1st Century Church certainly was not without error or the possibility of falling into error. And certainly there was no one saying that their tradition is infallible.
So, I thought since you use the word sacred with tradition implying holy and even infallible, I want to see how
How could anything that came from God be fallible? How can the Word of God be in error? Why would the Apostle instruct the faithful to “hold fast” to something that is fallible?
People in the Church make errors, but the divine bride of Christ is protected by Him and kept holy and blameless, though the fallible persons connected to her may become sick or fall. Those who depart from the Holy Foundation cannot change that foundation. The foundation remains immutable. That foundation contains the Holy Scripture and the Sacred Traditions (teachings of the Apostles preserved in the paradosis).
I don’t think that you can “see” this using the current definition you have for “church”
I did a little word study on the whole concept of oral tradition or tradition itself. There was not much to be said from the word of God.
I would not expect that you would. Sacred Tradition compliments the written scripture.
But, you cannot even accept the references to paradosis that are found in the Scripture, so it stands to reason you would not find much!
