Not all Scripture is the same level. There exists a hierarchy in which the actual words of Christ are supreme, followed closely by the accounts of the eye witnesses. Other works such as the Old Testament and the Paulian letters offer context and clarity. The Old Testament was satisfied by the death and resurrection of Christ. The letters of Paul and other subsequent documents, including the Catechism and Encyclicals offer clarity and insight.
Please refer to my post #4297 for the details of the Catechism on this.

CATECHISM OF THE CATHOLIC CHURCH
It would be nice if questions regarding the actual beliefs of the Church were first filtered through this magnificent tool. It is a lot of fun to get these question as they pop, disheveled, in your (plural-inclusive) heads, but if you want efficiency and precision, there you go first.
For ye have heard of my conversation in time past in the Jews' religion, how that beyond measure I persecuted the church of God, and wasted it: And profited in the Jews' religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers.
But when it pleased God, who separated me from my mother's womb, and called [me] by his grace, To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood: Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.
Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days. But other of the apostles saw I none, save James the Lord's brother. Galatians 1:11-19
