Logginos of Grigoriou

Logginos of Grigoriou, a hieromonk, with the secular name Constantine Papadimitriou, son of Demetrius, was born in the village of Nisani in Arta, Epirus, in 1858. He came to the Monastery of Saint Nicholas, called of Gregory after its venerable founder, in 1888. The next year he was tonsured a monk by the charismatic abbot Archimandrite Symeon (d. 1905). In 1901 he was ordained deacon and priest. For years he was steward and confessor at the monastery's dependency of the Holy Unmercenaries in Arta.

Elder Barlaam of Gregoriou, after the repose of the hieromonk Logginos, wrote: "A model of a truly very devout hieromonk. He had won the respect and love not only of the people of Arta, but of the whole county. He was regarded as an ideal confessor and in his days our little monastery revived the days of the Turkish occupation, being the spiritual nursery of the county of Arta." Truly the most devout Father Logginos of Gregoriou was an ideal confessor, who created an important spiritual movement, as in the time of the Turkish occupation, when a school functioned with Saint Theochares of Arta as teacher and one of his pupils, the well-⁠known Philhellene Nicholas Skoufas. He reposed in the Lord on 1 January 1936 at the dependency in Arta, where he had served with fervent zeal together with his elder Daniel for many years, helping the spiritual salvation of many Epirotes. He is venerated by the faithful, without synodal canonization.
