Philip the Apostle

Reading from the Synaxarion:

This Apostle, one of the Twelve, was from Bethsaida of Galilee, and
was a compatriot of Andrew and Peter. He was instructed in the
teachings of the Law, and devoted himself to the study of the prophetic
books. Therefore, when the Lord Jesus called him to the dignity of
apostleship, he immediately sought out and found Nathanael and said to him,
"We have found Him of Whom Moses in the Law and the Prophets did
write, Jesus of Nazareth, the son of Joseph" (John 1.45). Having
preached Jesus the God-man throughout many parts of Asia Minor, and having
suffered many things for His Name's sake, he was finally crucified upside
down in Hierapolis of Phrygia.

Apolytikion in the Third Tone
O Holy Apostle Philip, intercede with the merciful God that He
grant unto our souls forgiveness of offences.

Kontakion in the Plagal of the Fourth Tone
Your disciple and friend, emulator of Your passion, the divinely
eloquent Philip, proclaimed You to the world as God. By his entreaties,
and through the Theotokos, keep Your Church from lawless enemies, O
most merciful.
