2. Of the Holy Spirit

Almighty and most merciful God, grant, we beseech thee,
that by the indwelling of thy Holy Spirit we may be enlightened 
and strengthened for thy service; through Jesus Christ our 
Lord, who liveth and reigneth with thee, in the unity of the 
Holy Spirit, one God, now and for ever.  Amen.

*Preface of Pentecost*


3. Of the Holy Angels

O Everlasting God, who hast ordained and constituted the
ministries of angels and men in a wonderful order: Mercifully 
grant that, as thy holy angels always serve and worship thee in 
heaven, so by thy appointment they may help and defend us 
on earth; through Jesus Christ our Lord, who liveth and 
reigneth with thee and the Holy Spirit, one God, for ever 
and ever.  Amen.

*Preface of Trinity Sunday*


4. Of the Incarnation

O God, who didst wonderfully create, and yet more 
wonderfully restore, the dignity of human nature:  Grant 
that we may share the divine life of him who humbled 
himself to share our humanity, thy Son Jesus Christ; who 
liveth and reigneth with thee, in the unity of the Holy Spirit, 
one God, for ever and ever.  Amen.

*Preface of the Epiphany*
