Studying the Shroud of Turin:

[Ron Conte]

AB positive blood type is the universal recipient, O negative is the universal donor.

Jesus is figuratively able to receive from everyone their sins and so to purify them, making them holy and fit for heaven.

Reminds me of the following verse:

[Matthew]
{11:28} Come to me, all you who labor and have been burdened, and I will refresh you.

And His Church also welcomes everyone to refresh us.
