Indifferent to those who don’t have a tradition stemming from G-d and Moses. But you do, you do...
The Noahide nonsense has no basis in the scripture. Conversion in Biblical terms in the times before Christ never consisted of merely believing in a God, and following 7 laws. All of the pagan gods were condemned, and those who worship them with them. If anyone is to be saved, they therefore must put away idolatry and worship the true God. Why then would they not convert and take on the law of God too, if they have embraced the true God? And this embrace consisted of converting to the true church of God, not just in dry belief, but in active practice, its sacraments and signs, outside of which there is no salvation.
“And when a stranger shall sojourn with thee, and will keep the passover to the LORD, let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof. One law shall be to him that is homeborn, and unto the stranger that sojourneth among you.”
Remember me, O Lord, with the favour that thou bearest unto thy people: O visit me with thy salvation; that I may see the good of thy chosen, that I may rejoice in the gladness of thy nation, that I may glory with thine inheritance (Ps. 106:4, 5)
Outside of “His nation,” there is nothing.
