I’m having trouble understanding the whole basis for this question. As article 95 of the Catechism states, the bible cannot be uniquely removed or distinct from the deposit of Sacred Tradition, or the Teaching Magisterium of the Church any more than an element of the Holy Trinity can be isolated:
Article 95 - “It is clear therefore that, in the supremely wise arrangement of God, sacred Tradition, Sacred Scripture, and the Magisterium of the Church are so connected and associated that one of them cannot stand without the others. Working together, each in its own way, under the action of the one Holy Spirit, they all contribute effectively to the salvation of souls.”
So the real question here has to be to whom does the Word of God (being made up of both Sacred Tradition and Sacred Scripture) belong? And according to article 102, the one single uttered Word of God was Christ:
Article 102 - “Through all the words of Sacred Scripture, God speaks only one single Word, his one Utterance in whom he expresses himself completely: You recall that one and the same Word of God extends throughout Scripture, that it is one and the same Utterance that resounds in the mouths of all the sacred writers, since he who was in the beginning God with God has no need of separate syllables; for he is not subject to time.”
Article 103 continues to say - “For this reason, the Church has always venerated the Scriptures as she venerates the Lord’s Body. She never ceases to present to the faithful the bread of life, taken from the one table of God’s Word and Christ’s Body.”
For this reason, Sacred Scripture would belong to the Catholic Church…the one Church of the Body of Christ…the one Church that serves both the Word and Body from one table. This conclusion would seem to be supported by the following statement in article 105 of the Catechism:
Article 105 - “For Holy Mother Church, relying on the faith of the apostolic age, accepts as sacred and canonical the books of the Old and the New Testaments, whole and entire, with all their parts, on the grounds that, written under the inspiration of the Holy Spirit, they have God as their author and have been handed on as such to the Church herself.”
