It is an objective Truth we seek. Truth is not 'relative' to other competing truths, rather it is absolute and immutable.
We determine the true faith from the profane with the 'rule of faith'. If you are looking to the perfection of faith it would be ill advised to stop at Scripture as
Tradition combined with Scripture, Church comprised of her Bishops, her doctors, the Early Church Fathers, miracles and natural reason make up the whole and complete, sole, and infallible rule of faith.
The Church was entrusted with the entire deposit of faith;
"The apostles entrusted the "Sacred deposit" of the faith (the depositum fidei),[ cf. 1 Tim 6:20; 2 Tim 1:12-14 (Vulg.)] contained in Sacred Scripture and Tradition, to the whole of the Church. "By adhering to [this heritage] the entire holy people, united to its pastors, remains always faithful to the teaching of the apostles, to the brotherhood, to the breaking of bread and the prayers. So, in maintaining, practicing and professing the faith that has been handed on, there should be a remarkable harmony between the bishops and the faithful."[cf. Acts 2:42 (Greek)] [
CCC 84].
"Tradition" includes something other than 'oration' of God's word. It is a rational understanding of the Word of God conforming to the doctrine and dogma of an apostolic Church transmitted from one generation to the next. Thus, Sacred Tradition is combined with Sacred Scripture forming within us the fullness of faith. Christ's Kingdom is formed our of Moses’ remnant Kingdom. Christ formed His Kingdom first to teach the principles of a sole and infallible rule of faith. Within the infallible rule of faith lies the teaching authority given by Christ to the Church [Cf. Matthew 28:19]. The Catholic Church was commissioned by Christ to teach and baptize.
All of the New Testament is the Tradition of the Catholic Church. Separate it from the Catholic Tradition and you're left with a meaningless story of a mystic, faith becomes a diminished light or extinguished entirely. "
And having different gifts, according to the grace that is given us [the Church], either prophecy, to be used according to the rule of faith;" [Romans 12:6]. The Word is alive, made flesh to dwell among us. [Cf. John 1:14]. The Sacred Tradition includes the Word of God, still alive, and dwells within us in the appearance of bread and wine.
"God inasmuch as it is consigned to writing under the inspiration of the divine Spirit, while sacred tradition takes the word of God entrusted by Christ the Lord and the Holy Spirit to the Apostles, and hands it on to their successors in its full purity, so that led by the light of the Spirit of truth, they may in proclaiming it preserve this word of God faithfully, explain it, and make it more widely known." [Dei Verbum, 9]
