Anna Valerious: You ask a lot of questions.
Van Helsing: Normally I only ask two."What are we dealing with?" and "How do I kill it?"

Answer: Gabriel is the true name of the character described elsewhere as the Left Hand of God, responsible for Dracula's original death. Dracula uses this to try to remind Van Helsing of their history together. The implication is that Van Helsing is actually the archangel Gabriel, credited with (among other things) announcing the pending birth of Christ to Mary his mother, Joseph his father, and Elizabeth mother of John the Baptist.
