Pope Emeritus Benedict XVI leaves behind a theological legacy of extraordinary depth. His "Introduction to Christianity," written in 1968 as Joseph Ratzinger, remains one of the most important works of 20th-century theology — accessible yet profound, challenging yet comforting.
His pontificate was marked by an insistence on the "hermeneutic of continuity" in interpreting the Second Vatican Council, arguing that the Council must be read in light of the Church's entire tradition, not as a break from it.
His decision to resign the papacy in 2013 — the first papal resignation in nearly 600 years — demonstrated a profound humility and concern for the good of the universal Church.
