Moses’s mother was paid to nurse him and was part of his life throughout his childhood and western legalism is not something that eastern Christians agree with because eastern Christians are aware that Saint Paul used a completely different word that was translated as adoption but doesn’t mean legal adoption the way it’s practiced in the modern US. Your biblical scholarship being weak does not mean that I am blaspheming the Holy Spirit either.
It didn’t even mean legal adoption back in Saint Paul’s time either. This is not even something that’s debated by literally anyone who studies these things
