Antipascha
St Thomas Sunday
Troparion - Tone 7
From the sealed tomb, You did shine forth O Life!
Through closed doors You did come to Your disciples, O Christ God!
Renew in us, through them, an upright spirit,
By the greatness of Your mercy, O Resurrection of all!
Kontakion - Tone 8
Thomas touched Your life-giving side with an eager hand, O Christ God,
When You did come to Your apostles through closed doors.
He cried out with all: You are my Lord and my God!
And:
Apostle Thomas
Troparion - Tone 4
First-enthroned of the apostles,
teachers of the universe:
Entreat the Master of all
to grant peace to the world,
and to our souls great mercy!
Kontakion - Tone 2
Today Christ the Rock glorifies with highest honor
The rock of Faith and leader of the Apostles,
Together with Paul and the company of the twelve,
Whose memory we celebrate with eagerness of faith,
Giving glory to the one who gave glory to them!
Also:
Holy, Glorious Apostle Thomas
Troparion - Tone 2
You were a disciple of Christ
And a member of the divine college of Apostles.
Having been weak in faith you doubted the Resurrection of Christ.
But by feeling the wounds you believed in His all-pure passion:
Pray now to Him, O all-praised Thomas to grant us peace and great mercy.
Kontakion - Tone 4
Thomas, the faithful servant and disciple of Christ,
Filled with divine grace, cried out from the depth of his love:
You are my Lord and my God!
