Quinquagesimum natalem (1959.11.28)
This short Latin letter of John XXIII, issued on 28 November 1959, is an official congratulatory message addressed to Pietro Ciriaci on the fiftieth anniversary of his priestly ordination. John XXIII recalls their shared Roman seminary years, praises Ciriaci’s academic and diplomatic career, extols his service to the Roman Curia, highlights his role as Apostolic Nuncio in Czechoslovakia and Portugal, commends his work in interpreting the Tridentine decrees and handling “arduous” cases, and concludes by invoking divine light and strength so that Ciriaci may continue to labor for the “utility and honor” of the Roman See, extending an Apostolic Blessing to him and all connected to the jubilee.
