I bow to the ground before you and wish you in the name of the Lord good health, above all salvation and well-being, and may God save the fatherly Holy, Catholic, and Apostolic Church till the end of time from discord and herecies, the devious webs of enemies...
I bow before all with a great big request: I need someone to be my helper, I cannot survive alone, and it's not proper to live this way, spending whole weeks alone. Do not leave me for Christ's sake, have mercy on this miserable orphan, suffering in hardship.
A true believer is needed here, believing in Christ as the Old Believers do, and a male is needed to chop wood, cut down hay ... My health and strength have deteriorated.
The interesting thing to note is the terminology she uses in her first sentence to specifically define the church she believes in using the Four Marks of the Church (though she leaves out one), thus proclaiming the orthodoxy of the Old Believers' beliefs (also note that the term "Catholic" here in no way means "Roman Catholic"). One may even infer that the "devious webs" are being cast by the reformed Russian Orthodox Church.
I would also note that the archaic nature of some the terms she uses ("наипаче", "многокозненных сетей вражиих", "не добре", "седмицу"), and the archaic sentence structure is more consistent with the language used in the Russian Bible, rather than with the conventions of the early 20th century. The English equivalent would be the language found in the King James Bible.
A note to astral303: I noticed that you translated "сырая земля" as "raw earth", which is interesting, because while "сырой" means both "raw" and "damp", it most certainly is meant as "damp" when describing the earth. I know "raw earth" sounds more natural in English, but I think simply saying "ground" is the best equivalent, since I can't think of an English turn of phrase that invokes the connotations of describing the ground as damp in the intended manner.
