Pope Leo XIV appoints Sister Alessandra as envoy to Argentina, first nun in papal diplomatic role

Pope Leo XIV has named Sister Alessandra, an economist and head of the Dicastery for Promoting Integral Human Development, as his envoy to Argentina, marking a notable first for a nun in a papal diplomatic mission. She will visit La Matanza on October 27-28, a peri-urban area with significant social challenges. The appointment signals a potential shift in Vatican diplomatic practice, though its broader implications for Argentina-Vatican relations remain unclear.
