Faith and reason are like two wings on which the human spirit rises to the contemplation of truth.

Joseph Aloisius Ratzinger

1998 encyclical *Fides et Ratio* · Checked on 26 July 2026
Faith and reason are like two wings on which the human spirit rises to the contemplation of truth.

Analysis

The exact phrase appears in the introduction of *Fides et Ratio* (paragraph 1), authored by Pope John Paul II, not Joseph Ratzinger. However, the statement itself is verbatim from the document. Ratzinger (later Pope Benedict XVI) was Prefect of the Congregation for the Doctrine of the Faith at the time but did not author this encyclical.

Background

*Fides et Ratio* (Faith and Reason) is a 1998 encyclical by Pope John Paul II addressing the relationship between faith and philosophy. It emphasizes their complementary roles in seeking truth. Joseph Ratzinger was a prominent theologian but not the author of this text.

Verdict summary

The statement accurately quotes Pope John Paul II's 1998 encyclical *Fides et Ratio*.
