That doesn’t answer my question: Name one essential element that has been omitted from Scripture.
I’ve asked this in many threads and I’m still waiting …
The apostles did not omit any essential elements from the scriptures. But they left the Church many elements that still had to be made explicit and definitive. What the Church has made explicit and definitive as deposited in Scripture and contained in Tradition is not a “new revelation”. Church doctrines and dogmas serve to bring what is revealed in Scripture to a clearer light and fuller understanding of the Christian faith.
Consider Christ’s teaching on divorce: “It was also said, ‘Whoever divorces his wife must give her a bill of divorce.’ But I say to you, whoever divorces his wife (unless the marriage is unlawful) causes her to commit adultery, and anyone who marries a divorced woman commits adultery” (Mt 5:31-32). The Catholic Church understands this passage as a denial by Jesus of the legitamacy of divorce itself. These words of Jesus taken in connection with Mk 10:11-12 and Lk 16:18 indicate that he absolutely forbade divorce. And thus the Catholic Church absolutely forbids divorce among her members and does not recognize the legitimacy of civil divorce. Many Protestant denominations interpret the words of our Lord otherwise and understand Matthew’s “exceptive clause” as a modification of the absolute prohibition. And so many Protestant denominations permit divorce under relative circumstances. Yet Jesus rejected the Old Testament commandment that assumed divorce was legitimate as long as it was legal.
“The Christian economy, therefore, since it is the new and definitive Covenant, will never pass away, and no new public revelation is to be expected before the glorious manifestation of our Lord Jesus Christ” (DV,4; 1Tim 6:14; Titus 2:13). Yet even if revelation is already complete, it has not been made completely explicit; it remains for Christian faith gradually to grasp its full significance over the course of the centuries.
"Christ the Lord, in whom the entire Revelation of the most high God is summed up, commanded the apostles to preach the Gospel…In preaching the Gospel, they were to communicate the gifts of God to all men. This Gospel was to be the source of all saving truth and moral discipline (DV,7; Mt.28:19-20; Mk 16:15).
In keeping with the Lord’s command, the Gospel was handed on in two ways: ‘orally’ “by the apostles who handed on, by the spoken word of their preaching, by the example they gave, by the institutions they established, what they themselves had received - whether from the lips of Christ, from his way of life and his works, or whether they had learned it from the prompting of the Holy Spirit” (DV,7); ‘in writing’ “by those apostles and other men associated with the apostles who, under the inspiration of the Holy Spirit, committed the message of salvation to writing” (DV,7).
“In order that the full and living Gospel might always be preserved in the Church, the apostles left bishops as their successors. They gave them their own position of teaching authority” ( DV 7:1;St.Irenaeus, Adv. Haeres. 3,3,1

G 7/1,848)…
This living transmission, accomplished in the Holy Spirit, is called Tradition, since it is distinct from Sacred Scripture, though closely connected to it. Through Tradition “the Church in her doctrine, life and worship, perpetuates and transmits to every generation all that she herself is, all that she believes” (DV 8:1). “The sayings of the holy Fathers are a witness to the life-giving presence of this Tradition…” (DV 8:3)
The Father’s self-communication, made through his Word in the Holy Spirit, remains present and active in the Church: “God who spoke in the past, continues to converse with the Spouse of his beloved Son. And the Holy Spirit, through whom the living voice of the Gospel rings out in the Church - and through her in the world - leads believers to the full truth, and makes the Word of Christ dwell in them in all its richness” (DV 8:3; Col 3:16).
“Sacred Tradition and Sacred Scripture, then, are bound closely together, and communicate one with the other. For both of them, flowing out from the same divine well-spring, come together in some fashion to form one thing, and move towards the same goal” (DV 9). Each of them makes present and fruitful in the Church the mystery of Christ, who promised to remain with his own “always to the close of the age” (Mt 28:20).
