Option B:
O God, who in creating the human race
willed that man and wife should be one,
join, we pray, in a bond of inseparable love
these your servants who are to be united in the covenant of Marriage,
so that, as you make their love fruitful,
they may become, by your grace, witnesses to charity itself.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
one God, for ever and ever.
R./ Amen.
