The words of committal follow, one of two options given in OCF 219, or one of four options (a bit more specialized) given in OCF 406. Option A was included in the first edition of OCF. I’ll give the second, which borrows from the blessing of Aaron:
In sure and certain hope of the resurrection to eternal life through our Lord Jesus Christ,
we commend to Almighty God our brother/sister N.,
and we commit his/her body to the ground
[or the deep or the elements or its resting place]:
earth to earth, ashes to ashes, dust to dust.
The Lord bless him/her and keep him/her.
the Lord make his face to shine upon him/her and be gracious to him/her;
the Lord lift up his countenance upon him/her and give him/her peace.
According to the final rubric of OCF 219, the committal takes place at this time or at the conclusion of the rite.
