I read the part about IVF on another thread. It struck me again how isolated the GB is from the rest of the world. God favors life. Jesus does, too.
The GB fixation on Leviticus type details blinds to their eyes to the major themes of the Bible: Love and to Live Abundantly.
They make so many assumptions. I suppose they are so used to not being questioned. Any normal person would stop them in their tracks. How is life a bad idea. What is so bad about adultery? A penis and vagina interacting or the breaking of safety and trust in a marriage. Severe abuse is more certainlly adultery than mere sexual intercourse.
Their focus on itsy bitsy assumptions and meanderings through scripture that is far from express blinds them to the main messages of the Bible.
Of course, who are these men that tell married couples what to do? No one in the world's eyes. Do they have any special Bible training? No.
They need to get out of private marital matters. People must learn that parts of their lives are private. What would Jesus do? I strongly believe that Jesus would celebrate a new life and be so happy that a child would be raised by loving parents.
Leviticus does not make the Bible. Obscure verses do not make a whole theology.
