Interestingly, the Latin version of the encyclica is yet to be released at the moment

Modern encyclicals aren't written in Latin anymore. They're drafted in Italian and the title is the Latin translation of the incipit.

Indeed, the beginning of the Italian text is: "La magnifica umanità creata da Dio si trova oggi..." from which, Magnifica Humanitas.

Yeah, I don't know how they expect the people of Latin America to read this.
