Barring my faulty memory (and if I’m not lazy) I want to post prayers on Monday from all over Church History and then throughout the modern day, and then my own. This one comes from Book of Divine Worship (and the Book of Common Prayer) for Pentecost Sunday.
Almighty God, who on this day
didst open the way of eternal life
to every race and nation
by the promised gift of thy Holy Spirit:
Shed abroad this gift throughout the world
by the preaching of the Gospel,
that it may reach to the ends of the earth;
through Jesus Christ our Lord, who liveth and reigneth
with thee, in the unity of the Holy Spirit,
one God, for ever and ever.
