Ah, thou poor sinless child, accurst in the eyes of the people, God hath signified His care of thee, and in my heart I feel already something of that adoration which shall be thy due when for thy purity and holiness He shall bestow upon thy relics some signal mark of His favour, and the Church shall declare thee blessed!
The above is from "Monk and Hangman's daughter" by Ambrose Bierce (1911).
In the above sentence relics is 'the remains of a deceased person' in a dictionary. Thus, the sentence means God will bestow some sign on the body of the girl (a protagonist of the story) after her death, and the Church will grand some sort of 'woman saint' then ? (It's just my wild guess.)
Would somebody help me to understand this sentence, please!
