Reaching puberty doesn't mean someone is ready for marriage, especially with a 53 year old man
Many religions even today determine their law of marriage to be based on puberty.
A woman can get her puberty as early as 11, she is legally permitted in the religion to be married to a for example 53 year old man and consent to sex too.
Well consent doesn't matter here, because after marriage she is required to satisfy her old and dying husband anyway.
Not saying your religion supports that, but if it does support such a thing, you deserve to be put on a list and be kicked out of any secular country.
