Today, the Orthodox Church commemorates our Venerable Father Porphyrios of Kafsokalyvia († 2 December 1991).
Here you have an audio recording of the Divine Liturgy of May 27, 1977 in the Monastery of Saint Nicholas Kalissia, Penteli. Saint Porphyrios was 71 years old and the woman that was singing looks like is his sister.
Through the prayers of our Venerable Father Porphyrios, O Lord, save us!
