Ivan Vasilyevich was the Grand Prince of Moscow from 1533 to 1547, then “Tsar of All the Russias” until his death in 1584.
On November 19, 1581 Ivan became angry with his son’s pregnant wife, because of the clothes she wore, and beat her up. As a result she had a miscarriage. His son argued with his father about this beating. In a sudden fit of rage, Ivan the Terrible raised his iron-tipped staff and struck his son a mortal blow to the head.
Luke 23:33-34, 44-47
33 When they came to the place called the Skull, they crucified him and the criminals there, one on his right, the other on his left. 34 Then Jesus said, “Father, forgive them, they know not what they do.”
44 It was now about noon and darkness came over the whole land until three in the afternoon 45 because of an eclipse of the sun. Then the veil of the temple was torn down the middle.46 Jesus cried out in a loud voice, “Father, into your hands I commend my spirit”; and when he had said this he breathed his last. 47 The centurion who witnessed what had happened glorified God and said, “This man was innocent beyond doubt.”
