Would you please post these Scriptures - chapter and verse?
Again, your personal beliefs rely on only the Truth in the Bible, and so you ignore Truths that Jesus taught verbally.
Not all Truth is contained in the Bible.
Jesus taught by example and speaking and this was passed down by the Apostles and their successors.
Even today Catholic priests preach the Gospels verbally through the pulpit.
Jesus didn’t place a leather-bound New Testament directly into your hands. He created a Church, in which these texts were written, preserved, and passed on, under the ongoing guidance of the Holy Spirit. In other words, Jesus transmitted divine revelation via Tradition, so if you can’t trust Tradition, then you can’t trust the revelation.
Since Sacred Scripture is part of Sacred Tradition, that means Tradition is bigger. It tells us things about the Bible that the Bible doesn’t say about itself (for example, there’s nothing in the Bible that tells us which books belong in the Bible). The apostles recognized this about their own writings—that they were part of a broader transmission of the Faith.
That’s why, in 2 Thessalonians 2:15, St. Paul instructs his readers to “stand firm and hold to the traditions which you were taught by us, either by word of mouth or by letter.” The mode of transmission—written or unwritten—is irrelevant. It’s all Tradition.
Every Christian believes that he or she is called to pray for the world, to intercede and to mediate for others, to have a “ministry of reconciliation” (2 Cor. 5:18-19).
The faith of the Church is that the saints are not really dead, but are fully alive in Jesus Christ, who is life itself (John 11:25; 14:6) and the bread of life who bestows life on all who eat his flesh and drink his blood (John 6:35, 48, 51, 53-56). The saints are alive in heaven because of the life they have received through their faith in Christ Jesus and through their eating of his body and blood.
The book of Revelation shows the saints worshipping God, singing hymns, playing instruments, making requests to Christ to avenge their martyrdom, and offering prayers for the saints on earth (Rev. 4:10, 5:8, 6:9-11).
