1. Accept the divine, absolute, and literal truth of the Bible.
This is by far the most important step: If the Bible isn’t the literal and absolute truth, we might as well just give up the whole game right now.
2. Redefine «literal» when needed.
Yes, the Bible is a the literal word of God. We all know that from step one. But does this mean that every word is supposed to be taken literally? The answer is yes, except in those cases where it isn’t.
For example, the Bible clearly says that God hates homosexuality. That part is literal. The bible also says that God hates mixing different fibers in clothing. That part is not literal.
…the preferred situation by far is to have everything be literally true. In cases where this is unfortunately not possible, your job as an apologist is to properly interpret the nearly literal statements to make them figuratively literal and relevant again.
Many non-apologists incorrectly assume that since God wrote the Bible, it should be clear, concise, and without the need for interpretation. We apologists know better. The real skill is to know when the Bible is clear, concise and not needing interpretation, but also to know when it does.
So, God hating homosexuality is literal. God hating mixing diverse fibers in clothing is not literal. Perhaps it is a metaphor for not mixing with other races, or possibly it has to do with the way the ancients divided their world into categories, or following the practice of not mixing fibers was a sign of love for God, or it only applied to the ancients and not to modern people, etc. Which one you choose is not important. The important part is that you can now wear wool and linen at the same time without being sent to hell, but still know that Liberace is there.
