Collect (ECUSA):

Almighty and everliving God, in your tender love for the human race you sent your Son our Savior Jesus Christ to take upon him our nature, and to suffer death upon the cross, giving us the example of his great humility: Mercifully grant that we may walk in the way of his suffering, and also share in his resurrection; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.

Almighty and everliving God
you love all people,
and you gave us Jesus: to be like us, and to die for us,
showing us how generous and humble we ought to be.
Help us to be willing to suffer as he did,
and let us share in his resurrection;
through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
