Greco was born in Catanzaro in 1775. He was a laureate in theology (Naples 1819). He served as Vicar Capitular and Dean of the Cathedral Chapter of Catanzaro. He was then Vicar of the diocese of Oppido. He was elected bishop of San Marco Argentano e Bisignano on 3 May 1824, and consecrated in Rome on 9 May by Cardinal Francesco Bertazzoli. He restored the façade of the cathedral and the episcopal palace of San Marco (1835), as well as that of Bisignano. He died in San Marco on 22 February 1840 and was interred in the Cathedral. His brother Ignacio was Bishop of Oppido (1819–1821). Leonardo Calabretta (2004). Le diocesi di Squillace e Catanzaro. Cardinali, arcivescovi e vescovi nati nelle due diocesi (in Italian).

The notion espoused by David M. Cheney, that San Marco was formed within the Metropolitan Archdiocese of Rossano is contrary to the evidence and to scholarly opinion, and cannot be maintained. In the Diatyposis of Leo the Wise (c. 900), an official list of episcopal Seats, the diocese of Rossano is entered as a suffragan of the Metropolitan of Reggio Calabria, both of whom are subordinate to the Patriarch of Constantinople (L. Duchesne, p. 9). In the Liber Censuum (c. 1192) Rossano is listed as a See dependent upon the Holy See, along with four other bishoprics in northern Calabria: Cassano, Bisignano, Cosenza, and Malvito. Bisignano, Cosenza and Malvito were suffragans of the Archbishop of Salerno. Paul Fabre, Le Liber Censuum de l'Église romaine I (Paris: Fontemoing 1905), p. 243 and 247. Malvito was not suffragan to Rossano. Louis Duchesne, Melanges Paul Favre, p. 14, points out that, if Rossano were an archdiocese, it was an autocephalous Greek archdiocese.
