If someone believes something to be biblical, it does not excuse them if it’s wrong. Would you say that leadership is excused from lying if they believe it’s biblical to lie to increase donations?
Many sins are committed out of ignorance. It doesn’t mean we don’t repent of them once we realize what we’ve done. Think of King Josiah in 2 Kings 22-23. All that time, Israel was living without the law, but when they found it and read it, Josiah tore his clothes. He grieved deeply. It didn’t matter that the nation of Israel had sinned out of ignorance. What mattered was that they had sinned, and now they needed to repent and fix it.
Also observe Jesus’s words in Matthew 20:25-28: “But Jesus called them to him and said, ‘You know that the rulers of the Gentiles lord it over them, and their great ones exercise authority over them. It shall not be so among you. But whoever would be great among you must be your servant, and whoever would be first among you must be your slave, even as the Son of Man came not to be served but to serve, and to give his life as a ransom for many.’” And we are to submit to one another (Ephesians 5:21).
Even if the military chain of command and the way they “own” you 24/7 is analogous to Jesus’s total authority over our lives, it is not analogous to how elders and bishops (pastors) in the church are to lead.
“Biblical authority is limited by the commandments of Scripture. Your spiritual leaders have no authority over you beyond what the Bible demands. For example, if your leader demands that you and your spouse have only one child, or that you entrust to his care all of your possessions, or anything not commended in Scripture, you are free to respectfully decline. God, not man, decides the parameters of authority.” from Walter Henrichsen’s Thoughts from the Diary of a Desperate Man
