"To summarize your believes..."
wrong... you've misunderstood and misrepresented me..
Either something is inspired or it isn't. There are a couple of places where text which was not in the original manuscripts was recorded in later manuscripts, and have been included in bibles and documented for what they are. If you didn't know about them, you probably just haven't been looking closely at the pages of your bible. If a variant is not inspired by God, it MIGHT be true, it might not be. You've misunderstood me there. a variant might at least be considered church tradition even if it's not the inspired word of God. But the variants in the bible are insignificant and don't present a different message. The majority of textual variants are things like spelling and word order, which are completely invisible once translated to English. For example, Greek uses a different case system where word order is not important, so some manuscripts switch the word order around because there is no meaning difference with word order changes in that language. it is nevertheless a textual variant, and Christians have known of these types of things all along.
Everyone is ignorant in one way or another, you seem to think I use the term 'ignorance' as a pejorative, but I'm speaking of it in the literal sense, not an affectual one. But it is a pretty basic concept in Bible study. It's not like you have to find a $400 scholarly book to find out about variants. It's in practically every bible. Anyone who is serious about their Bible study would at least look at the footnotes, but most would read numerous bible commentaries and versions if they study the Bible religiously.
"Is this how you believe that the Almighty has chosen to communicate with all of mankind?"
Well the textual transmission of scripture IS how he communicated to our generation, what I think about what might be a better way is irrelevant, God's ways are higher than ours. I would never have thought of defeating spiritual powers through Jesus allowing himself to be crucified. Making a God to suit yourself is basically idolatry, a violation of one of the ten commandments.
Consider the words of Jesus in regards to your question about why God would communicate in a cryptic way:
Matthew 13:10-13 "Then the disciples came and said to him, "Why do you speak to them in parables?" And he answered them, "To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given. For to the one who has, more will be given, and he will have an abundance, but from the one who has not, even what he has will be taken away. This is why I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand."
Someone else had posted these verses earlier, but they are relevant, especially 1st Corinthians:
Proverbs: 25:2 It is the glory of God to conceal things, but the glory of kings is to search things out.
1Corinthians 1:18-25 "For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God. For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent. Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world? For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe. For the Jews require a sign, and the Greeks seek after wisdom: But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God. Because the foolishness of God is wiser than men; and the weakness of God is stronger than men."
"Why devote so much time to deciphering the nuances in Bible passages when these verses are all that you need to know? "
Christians view the Bible as God's word, they love God, so they want to know as much about him as they possibly can. Christians have a relationship with God, listening to his word is how they get closer to him. Sure it's complicated, but human relationships can be complicated too. But a lot of times Christians are just on the defensive responding to attacks on the Bible by people who hate God's word, which forces Christians to have an understanding of the nuances. A lot of the early church councils which discussed a lot of nuances were formed in response to heresies from other groups such as Gnostics and Pelagians. There is also a Biblical command to Christians:
2 Timothy 2:15 "Do your best to present yourself to God as one approved, a worker who has no need to be ashamed, rightly handling the word of truth."
Is there ever a time when a violent act might be justified to you? My take is that all of mankind has sinned and is worthy of God's wrath, so anything less than the wrath of God is actually a form of mercy. so when ungodly nations (who torture babies and throw them in the fire for their gods/idols) are killed by God through war, it was actually a period of time that they were not in hell, so it is not the full punishment they deserved from a truly holy God who requires perfection in holiness. The real question should be why doesn't God judge everyone for their sin immediately instead of being patient with them, and the answer would be because he is merciful. 2Peter 3:9 "The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance."
