The then Cardinal Joseph Ratzinger referred to del Portillo's "modesty and availability in every circumstance,” in his work at the Congregation for the Doctrine of the Faith, which del Portillo "enriched in a singular way with his competence and experience.”
Tolleaegne kardinal Joseph Ratzinger osutas Alvaro del Portillo „tagasihoidlikkusele ning kättesaadavusele igas olukorras,“ tema tööle Usudoktriini Kongregatsioonis, mida Alvaro del Portillo „rikastas ainulaadsel moel oma kompetentsuse ja kogemusega“.
