But there was a time and a place after the death of our Lord when it was acceptable for heresy?
Perhaps depending on the specific circumstance and societal implications
Just to clear things up you mean 1000BC correct?
Yes
Not for heresy, no. It’s never been okay.
Exodus 21:23-25
But if there is harm, then you shall pay life for life, eye for eye, tooth for tooth, hand for hand, foot for foot, burn for burn, wound for wound, stripe for stripe.
Romans 13:1-14
Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God. Therefore whoever resists the authorities resists what God has appointed, and those who resist will incur judgment. For rulers are not a terror to good conduct, but to bad. Would you have no fear of the one who is in authority? Then do what is good, and you will receive his approval, for he is God’s servant for your good. But if you do wrong, be afraid, for he does not bear the sword in vain. For he is the servant of God, an avenger who carries out God’s wrath on the wrongdoer. Therefore one must be in subjection, not only to avoid God’s wrath but also for the sake of conscience.
Exodus 21:15
“Whoever strikes his father or his mother (mother church???) shall be put to death.
The death penalty is clearly stated for the following (which an advocate of could probably be labeled a heretic)
Worshiping other gods (Deuteronomy 13:6-13:10, Exodus 22:20)
Witchcraft (Exodus 22:18)
Taking God’s name in vain or cursing God’s name (Leviticus 24:16)
Cursing a parent (Exodus 21:15, 2:17, Leviticus 20:9, and in the New Testament Mark 7:10)
A woman who is found not to have been a virgin on the night of her wedding (Deuteronomy 22:13-22) (in Judaism, this is traditionally understood as referring to a woman who committed adultery while betrothed)
