Perhaps Protestants here would like to tell us about this.
How do you understand scripture without referring to the relevant traditions that came with it?
Scripture is a concealed and closed book for those without the Spirit. It is only by the Spirit of God through illumination that someone can progressively grow in knowledge of the Scriptures. Spiritual blindness is as real as the air that we breathed. You must be born again to understand the Scriptures.
Luke 24:45
Then he opened their minds to understand the Scriptures,
Wisdom from the Spirit - 1 Cor 2
6 Yet among the mature we do impart wisdom, although it is not a wisdom of this age or of the rulers of this age, who are doomed to pass away. 7 But we impart a secret and hidden wisdom of God, which God decreed before the ages for our glory. 8 None of the rulers of this age understood this, for if they had, they would not have crucified the Lord of glory. 9 But, as it is written,
“What no eye has seen, nor ear heard,
nor the heart of man imagined,
what God has prepared for those who love him”—
10 these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God. 11 For who knows a person’s thoughts except the spirit of that person, which is in him? So also no one comprehends the thoughts of God except the Spirit of God. 12 Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God. 13 And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.

14 The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. 15 The spiritual person judges all things, but is himself to be judged by no one. 16 “For who has understood the mind of the Lord so as to instruct him?” But we have the mind of Christ.
Luke 10:21
21 In that same hour he rejoiced in the Holy Spirit and said, “I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and revealed them to little children; yes, Father, for such was your gracious will.
2 Peter 3:16
16 as he does in all his letters when he speaks in them of these matters. There are some things in them that are hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures.
Matthew 22:29
29 But Jesus answered them, “You are wrong, because you know neither the Scriptures nor the power of God.
John 5:39
39 You search the Scriptures because you think that in them you have eternal life; and it is they that bear witness about me,
