dear (adj.) Old English deore "precious, valuable, costly, loved, beloved," from Proto-Germanic deurjaz (source also of Old Saxon diuri, Old Norse dyrr, Old Frisian diore, Middle Dutch dure, Dutch duur, Old High German tiuri, German teuer), further etymology unknown. Used interjectorily since 1690s. As a polite introductory word to letters, it is attested from mid-15c. As a noun, from late 14c., perhaps short for dear one, etc.—Online Etymology Dictionary
From the Roman Canon (Ordinariate translation)
Vouchsafe, O God, we beseech thee, in all things to make this oblation blessed, approved, and accepted, a perfect and worthy offering; that it may become for us the Body and Blood of thy dearly beloved Son, our Lord Jesus Christ.
Prayer of Humble Access (Ordinariate Divine Worship)
We do not presume to come to this thy Table, O merciful Lord, trusting in our own righteousness, but in thy manifold and great mercies. We are not worthy so much as to gather up the crumbs under thy Table. But thou art the same Lord whose property is always to have mercy. Grant us therefore, gracious Lord, so to eat the flesh of thy dear Son Jesus Christ, and to drink his Blood, that our sinful bodies may be made clean by his Body, and our souls washed through his most precious Blood, and that we may evermore dwell in him, and he in us. Amen.
Prayer After Communion (Ordinariate Divine Worship)
Almighty and everliving God, we most heartily thank thee for that thou dost feed us, in these holy mysteries, with the spiritual food of the most precious Body and Blood of thy Son our Saviour Jesus Christ; and dost assure us thereby of thy favour and goodness towards us; and that we are very members incorporate in the mystical body of thy Son, the blessed company of all faithful people; and are also heirs, through hope, of thy everlasting kingdom, by the merits of the most precious death and Passion of thy dear Son. And we humbly beseech thee, O heavenly Father, so to assist us with thy grace, that we may continue in that holy fellowship, and do all such good works as thou hast prepared for us to walk in; through Jesus Christ our Lord, to whom, with thee and the Holy Spirit, be all honour and glory, world without end. Amen.
The Order for the Celebration of Holy Matrimony for use by the Ordinariates erected under the auspices of the Apostolic Constitution Anglicanorum cœtibus
Dearly beloved, we are gathered here in the sight of God and in the presence of this congregation, to witness the joining together of this man and this woman in Holy Matrimony; which is an honourable estate, instituted of God himself, signifying unto us the mystical union that is betwixt Christ and his Church; which holy estate Christ adorned and beautified with his presence, and first miracle that he wrought, in Cana of Galilee, and is commended in Holy Writ to be honourable among all men; and therefore is not by any to be enterprised, nor taken in hand, unadvisedly, lightly, or wantonly; but reverently, discreetly, soberly, and in the fear of God, duly considering the causes for which Matrimony was ordained.
Angel of God, my guardian dear, to whom God’s love commits me here, ever this day be at my side, to light and guard, to rule and guide.
