Troparion of the Apostle Thaddeus, Tone 4
O holy disciple and witness to God who appeared in the flesh for our sakes, thou didst bring the light of saving grace to those in darkness, thou wast revealed as an excellent physician to the people of Edessa. Wherefore shelter those who fervently seek thee.
Kontakion of the Apostle Thaddeus, Tone 4
The Church has acquired thee as a star, O Thaddeus, and is ever enlightened by thy miracles. Save those who faithfully venerate thy memory.
