You mentioned Mary lost her salvation when she was “to take charge of Jesus” because [she wrongly thought] he lost his mind. Universal salvation did not begin until Jesus died on the cross, which makes your statement wrong about her losing salvation.
[Bible Answer] Greetings in Jesus’ name. Numerous people had salvation before Jesus died on the cross, including Mary at one point. For some strange reason, it seems few know people had salvation then. Here is Biblical proof for you to verify:
Then Jesus said to her, “Your sins are forgiven.” The other guests began to say among themselves, “Who is this who even forgives sins?” Jesus said to the woman, “Your faith has saved you; go in peace.” (Luke 7:48-50)
But Zacchaeus stood up and said to the Lord, “Look, Lord! Here and now I give half of my possessions to the poor, and if I have cheated anybody out of anything, I will pay back four times the amount.” Jesus said to him, “Today salvation has come to this house, because this man, too, is a son of Abraham. For the Son of Man came to seek and to save what was lost.” (Luke 19:8-10)
Then my soul will rejoice in the LORD and delight in his salvation. (Psa 35:9)
Restore to me the joy of your salvation and grant me a willing spirit, to sustain me. (Psa 51:12)
You used the term Universal Salvation, which is another word for Universalism (the faulty belief that all will be saved). IF that is your belief, please be assured that many people will go to fiery torment, even though Jesus died for all. Here are a few Scriptures:
The Son of Man will send out his angels, and they will weed out of his kingdom everything that causes sin and all who do evil. They will throw them into the fiery furnace, where there will be weeping and gnashing of teeth. (Mat 13:41,42)
Then he will say to those on his left, “Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels.” (Mat 25:41)
Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor homosexuals, nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God. (1 Cor. 6:9,10, NASB)
In a similar way, Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion. They serve as an example of those who suffer the punishment of eternal fire. (Jude 1:7)
The truth is, Mary became an unbeliever (when she wrongly thought Jesus was crazy) and lost her salvation because of it, according to Mark 3:21-35! Later she got her salvation back again.
