Sure, there are many interpretations of various interpretations of various Bible passages and of many doctrines. But in the end, it's for the Magisterium to settle disputes when it must. Protestants have no Magisterium.
Consider the dogma that during Holy Mass, bread and wine become Christ's body and his blood. Protestants usually think Our Lord speaks metaphorically about that change in John 6. They'll tell us that we're idolators who "worship wafers."
That's partly because they believe Luther's novel "sola scriptura" doctrine. It's novel because he invented it. You won't find it in any document from the Early Church. But if you read St. Ignatius of Antioch's 2nd-century letter to the Smyrnaeans where he warned them to avoid anyone who denied that bread changed into Christ's body and blood.
He wrote:
"Chapter 6. Unbelievers in the blood of Christ shall be condemned
Let no man deceive himself. Both the things which are in heaven, and the glorious angels, and rulers, both visible and invisible, if they believe not in the blood of Christ, shall, in consequence, incur condemnation. He that is able to receive it, let him receive it. Matthew 19:12 Let not [high] place puff any one up: for that which is worth all is faith and love, to which nothing is to be preferred. But consider those who are of a different opinion with respect to the grace of Christ which has come unto us, how opposed they are to the will of God. They have no regard for love; no care for the widow, or the orphan, or the oppressed; of the bond, or of the free; of the hungry, or of the thirsty.
Chapter 7. Let us stand aloof from such heretics
They abstain from the Eucharist and from prayer, because they confess not the Eucharist to be the flesh of our Saviour Jesus Christ, which suffered for our sins, and which the Father, of His goodness, raised up again. Those, therefore, who speak against this gift of God, incur death in the midst of their disputes. But it were better for them to treat it with respect, that they also might rise again. It is fitting, therefore, that you should keep aloof from such persons, and not to speak of them either in private or in public, but to give heed to the prophets, and above all, to the Gospel, in which the passion [of Christ] has been revealed to us, and the resurrection has been fully proved. But avoid all divisions, as the beginning of evils."

If Dr. Craig rode a Time Machine to St. Ignatius's diocese, people there wouldn't have thought he was a Christian. Instead, they would have believed he was a heretic.

Catholics pay attention to what the Early Church believed. But many Protestants ignore it because they believe sola scriptura.
Years ago, I emailed with a Seventh-Day Adventist about "soul sleep." I quoted St. Justin Marty's 2nd-century First Apology to show that he believed that disembodied souls stayed awake. So, the Adventist replied, "That doesn't matter. We have the Bible."
