The Catholic Church bases her teaching upon one source: The word of God. This divine revelation is transmitted in two ways: through Scripture and apostolic tradition. Many assume that only the writings of the apostles are the word of God. However, their oral transmission of the Faith is also considered the word of God (1 Thess. 2:13).
Few Protestant groups today accept the validity, let alone the authority, of tradition. In fact, many believe that Scripture is the only definitive source of divine truth. For this reason, they are critical of certain doctrines of the Catholic Church that, according to them, have no basis in Scripture, such as the Real Presence and the existence of purgatory. However, these teachings are reflected in Scripture, as the passages we will look at illustrate.
Under each Catholic doctrine in the list that follows are passages from Scripture that witness to the doctrine’s divine origin. For the Catholic, what follows will make clear the harmony of Scripture and tradition: truth cannot contradict truth.

“‘Truly, truly, I say to you, he who believes has eternal life. I am the bread of life. Your fathers ate the manna in the wilderness, and they died. This is bread which comes down from heaven, that a man may eat of it and not die. I am the living bread which came down from heaven; if any one eats of this bread, he will live for ever; and the bread which I shall give for the life of the world is my flesh.’ The Jews then disputed among themselves, saying, ‘How can this man give us his flesh to eat?’ So Jesus said to them, ‘Truly truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you; he who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. For my flesh is food indeed, and my blood is drink indeed’” (John 6:47-55).
“For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, ‘This is my body which is for you. Do this in remembrance of me.’ In the same way also the cup, after supper, saying, ‘This cup is the new covenant of my blood. Do this, as often as you drink it, in remembrance of me.’ For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes” (1 Cor. 11:23-26).

“And I tell you, you are Peter, and on this rock I will build my Church, and the powers of death shall not prevail against it.

“For if he were not expecting that those who had fallen would rise again, it would have been superfluous and foolish to pray for the dead.

“Make friends quickly with your accuser, while you are going with him to court, lest your accuser hand you over to the judge, and the judge to the guard, and you be put in prison; truly, I say to you, you will never get out till you have paid the last penny” (Matt. 5:25-26).
“Each man’s work will become manifest; for the Day will disclose it, because it will be revealed with fire, and the fire will test what sort of work each one has done.
