III. For all Chistians in their vocation

Almighty and everlasting God, by whose Spirit the whole
body of thy faithful people is governed and sanctified:
Receive our supplications and prayers, which we offer before
thee for all members of thy holy Church, that in their
vocation and ministry they may truly and devoutly serve thee;
through our Lord and Savior Jesus Christ, who liveth and
reigneth with thee, in the unity of the same Spirit, one God,
now and for ever. Amen.

16. For the Mission of the Church

O God, who hast made of one blood all the peoples of the
earth, and sent thy blessed Son to preach peace to those
who are far off and to those who are near: Grant that people
everywhere may seek after thee and find thee, bring the
nations into thy fold, pour out thy Spirit upon all flesh, and
hasten the coming of thy kingdom; through the same thy
Son Jesus Christ our Lord, who liveth and reigneth with thee
and the Holy Spirit, one God, now and for ever. Amen.

or this

O God of all the nations of the earth: Remember the
multitudes who have been created in thine image but have
not known the redeeming work of our Savior Jesus Christ;
and grant that, by the prayers and labors of thy holy Church,
they may be brought to know and worship thee as thou hast
been revealed in thy Son; who liveth and reigneth with thee
and the Holy Spirit, one God, for ever and ever. Amen.
