Although St. Paul does not use the word church in Tim 3, 14 – 1 5, it suggests it, along with its authority, to teach, exhort, and even excommunicate heretical members if necessary. Tim 4, 1 1 – 1 6 we see St. Paul commemorating St. Timothy, the young bishop, the teaching authority which he has by virtue of his episcopal office. But this special authority and duty to teach, which Paul mentions to Timothy, extends to the Magisterium of the Church as a whole, i. j. to all the bishops in the world who they teach the faith in communion with the Bishop of Rome. The term house of God is appropriate for the description of the Church.
Saint Peter uses this image in 1 Pt 4, 1 7
in his encouragement to persecuted and suffering Christians.
Church: a sign of unity In John 17, 2 0 – 2 1 is the main idea Christ’s unity prayer, the unity of Christians: “Father … well, I ask not only for them, but also for those who through their word believe in me to they were all one as you, Father, in me and me in you, that they too may be one in us, that the world may believe that you sent me. “To achieve this Christ established his Church as a visible sign of his presence in all ages and a unifying power in the lives of those who they love and remain in it. “Stay in me and me in you. As a branch, it cannot bear fruit on its own unless it remains in the vineyard neither do you, unless you remain in me. I’m a vine, you are the branches. Who abides in me, and I in him, bears many fruit; for without me you cannot to do nothing “(John 15: 4-5). This unity in Christ and through Christ, which the Church shows, is not it is not only the unity of believers, but also the unity of teaching. For the last two thousand years, the Catholic Church has embodied the “fullness of the Christian faith.” And this is where the Christian he will find true unity with Christ, with other Christians, and with the teachings of Christ passed on to the Church (compare  Matthew / 28, 18-20). * Roman 16: 17-18: “Please, brethren, give beware of those who provoke strife and offense in opposition to the teachings which you have received, and avoid them. For they do not serve Christ ours To the Lord, but to His belly, and with sweet words and with deceit they deceive the hearts of the innocent. “* 1 Cor 1:10: “I beseech you, brethren, for a name our Lord Jesus Christ, all say the same thing, that there be no divisions among you, but that ye should be perfect in the same mind, and in the same judgment. ”

In Titus 1: 4-16, as well as in the Apostolic Letters to Timothy, we see St. Paul speaking with another bishop – Tito on the importance of unity in the teaching of the Church. It also emphasizes the authority and duty of the bishop to teach the gospel faithfully and accurately and to choose a capable man as his follower in the role of bishop.
