Their pioneering work resulted in an NFP method that is tested, easy to learn, and easy to use.   Because of this, they were able to touch more than four thousand couples in Bukidnon and other nearby provinces. The Vatican got to know about the Porsuelo’s “home-grown” NFP technology  and invited Eli and Feling Porsuelo  to explain the technology they had developed. The Porsuelos were cross-examined  by an international panel of doctors  in several sessions, a test which they passed  with flying colors. The Pope later referred to Feling as a ‘scientist’.

        Eventually,  the Vatican appointed them  to the Pontifical Council of the Family  to represent the Philippines, a position they held for ten years, during which time the Church got  valuable inputs towards understanding the true nature of NFP and how it advances Humanae Vitae values  that strengthen marriage. They were then the only Filipino couple in the Pontifical Council for Family and Life. ●
