Book of Common Prayer (page 347)

Ascension

Through thy dearly beloved Son Jesus Christ our Lord; who
after his glorious resurrection manifestly appeared to his
disciples; and in their sight ascended into heaven, to prepare
a place for us; that where he is, there we might also be, and
reign with him in glory.

Pentecost

Through Jesus Christ our Lord; according to whose true
promise the Holy Ghost came down [on this day] from
heaven, lighting upon the disciples, to teach them and to lead
them into all truth; uniting peoples of many tongues in the
confession of one faith, and giving to thy Church the power
to serve thee as a royal priesthood, and to preach the Gospel
to all nations.

Prefaces for Other Occasions

Trinity Sunday

For with thy co-eternal Son and Holy Spirit, thou art one God,
one Lord, in Trinity of Persons and in Unity of Substance;
and we celebrate the one and equal glory of thee, O Father,
and of the Son, and of the Holy Spirit.

All Saints

Who, in the multitude of thy saints, hast compassed us about
with so great a cloud of witnesses, that we, rejoicing in their
fellowship, may run with patience the race that is set before
us; and, together with them, may receive the crown of glory
that fadeth not away.
