I know I can’t change the post, but I will ask a mod to help with the title line.
Maybe the three witnesses for us on earth are what the Church refers to as the Baptism of desire (My soul is thirsting for the living God); the Baptism of water, as we know it; the Baptism of blood (Martyrdom, like the Holy Innocents suffered when Jesus was a baby) that Fr. Mitch Pacwa speaks of sometimes. Just a thought.
