Dear Nonna,
Your question is in the correct topic area.
I will ask that one of our esteemed priests and/or deacons answer your question for fear of providing incorrect information. But here is some information to start.
com�mend ( P ) Pronunciation Key (k-mnd)
tr.v. com�mend�ed, com�mend�ing, com�mends
To represent as worthy, qualified, or desirable; recommend.
To express approval of; praise. See Synonyms at praise.
To commit to the care of another; entrust.
I personally take the statement and use the thrid meaning, entrust, as in:
let us entrust ourselves and each other and all our life unto Christ our God."
To give of yourself, your entire, whole full self, body and soul to Christ and to trust in Him fully, with your life.
Alas, I cannot answer the rest of your question though. sorry
Michael
