Hi Annie,
Here is my assessment:
The conversions are not to authentic Catholicism - the one True Faith outside of which there is no salvation.
If people are converting to the schismatic Orthodox Coptic Church how can it be from God?
Our Lady would not appear to bring people to a schismatic Church that is not her Son's one True Church.
Purported miracles both great and small can be from the Deceiver.
Please be careful.
The Devil knows how to present evil as good.
I can see how these events can undermine a person’s Faith, leading them to believe that God, through Mary, is bringing people to the schismatic condemned Orthodox Religion. People will be deceived into believing that the Orthodox Religion is approved by God. But that would be a contradiction. God can't do that. He has already told us to be of the Church of his only Begotten Son - the Catholic Church.
Beware! Satan can appear as Mary, and even perform fake miracles. It has happened before. It stands to reason that it will be more commonplace and on a grander scale in this era where Satan has power in this world that is unprecedented since before Christ walked this earth.
We can't trust in ourselves, we need to follow Our Lord's directives and those of Holy Mother Church. Thankfully we know that we can be saved without believing any of the modern-day apparitions. Even if they appear to our weak intellects to be genuine, we do not NEED them, so best to keep SAFE. To be saved we must keep the Faith, and these apparitions are a threat to it.
