Maria Corina Machado is in hiding to avoid being shot or abducted by the Venezuelan government, but she is also on a political high. The de facto leader of Venezuela’s democratic opposition, Ms. Machado was announced as this year’s Nobel Peace Prize laureate this month. Last week she celebrated an event whose significance in her beleaguered land extends well beyond the spiritual: the canonization by Pope Leo XIV of two of her compatriots, the first Catholic saints in Venezuelan history.
