According to Pope Francis there is no sin that God cannot pardon. All we need to do is ask for forgiveness
Discussion
God pardoning and Biden pardoning are not the same. If Fauci asks forgiveness from Christ he is granted it, but it requires him to actually ask it. More than that, receiving forgiveness from sin doesn't absolve a man from still facing earthly justice. His sin can be removed and he can also rightly be justly sentenced for crimes committed. A wicked man being preemptively pardoned by another wicked man is not justice.
That all said, I so genuinely hope Fauci repents of his sins. And I pray for God's perfect and just will to be done in his timing.
