Primo Feliciter was a motu proprio issued by Pope Pius XII on March 12, 1948.[1]

Primo Feliciter was issued a year after the constitution Provida Mater Ecclesia. This motu proprio confirmed and blessed secular institutes within the Catholic Church.[1]

Along with Provida Mater Ecclesia and Cum Sanctissimus, Primo Feliciter provided the basis for Catholic secular institutes to receive their own legislation.[2]
