If there a body of “oral Tradition” that stands on equal authority with the written Scriptures where may we find these traditions and would not these traditions of necessity be in FULL AGREEMENT with the written word?
“Paul illustrated what tradition is: “For I delivered to you as of first importance what I also received, that Christ died for our sins in accordance with the scriptures. . . . Whether then it was I or they, so we preach and so you believed” (1 Cor. 15:3,11). The apostle praised those who followed Tradition: “I commend you because you remember me in everything and maintain the traditions even as I have delivered them to you” (1 Cor. 11:2).
What traditions were those? What traditions did Paul pass on to them orally that are not found in written Scripture?
How do we know?
“He commissioned them, saying, “Go therefore and make disciples of all nations” (Matt. 28:19).
They were to make disciples for Christ by teaching what Christ had taught, commanded, so is there some tradition or set of traditions that Christ taught that must be taught IN ADDITION to what the written Scriptures teach as
Christ's commandments? If so what are these traditions?
First of all, remember that Paul was not one of the twelve apostles; he received the teaching of Christ orally. Hence, everything he passed on was already oral tradition. Some of what Paul taught is recorded in Scripture.
Secondly, "Tradition" does not refer to legends or mythological accounts, nor does it encompass transitory customs or practices which may change, as circumstances warrant, such as styles of priestly dress, particular forms of devotion to saints, or even liturgical rubrics. Sacred or apostolic tradition consists of the teachings that the apostles passed on orally through their preaching. These teachings largely (perhaps entirely) overlap with those contained in Scripture, but the mode of their transmission is different.
How do we know?
They have been handed down and entrusted to the Church. It is necessary that Christians believe in and follow this tradition as well as the Bible (Luke 10:16). The truth of the faith has been given primarily to the leaders of the Church (Eph. 3:5), who, with Christ, form the foundation of the Church (Eph. 2:20). The Church has been guided by the Holy Spirit, who protects this teaching from corruption (John 14:25-26, 16:13).
They were to make disciples for Christ by teaching what Christ had taught, commanded, so is there some tradition or set of traditions that Christ taught that must be taught IN ADDITION to what the written Scriptures teach as Christ's commandments? If so what are these traditions?
If I understand your question correctly, you are asking how do we determine what constitutes authentic tradition. How can we know which traditions are apostolic and which are merely human?
