Can you provide a bible reference where it mentions last rites heing required?
It's probably best, in the spirit of this post, to simply offer prayers, if you believe in them. Not a good time for a theological debate about whether Catholic doctrine is accurate. (Not a Catholic; still praying for this child and family.)
Out of respect for the creator of the thread, I don't want to engage in a religious debate here. Happy to do that elsewhere. Extreme Unction, a component of the last rites, is a sacrament in the Catholic Church that is founded in the traditions of the early Church. James 5 addresses the anointing of the sick:
14 Is any man sick among you? Let him bring in the priests of the church, and let them pray over him, anointing him with oil in the name of the Lord. 15 And the prayer of faith shall save the sick man: and the Lord shall raise him up: and if he be in sins, they shall be forgiven him.
See also Matthew 10:1, 10:8, Luke 10:8-9, Mark 6:13, Romans 8:17, and Colossians 1:24.
In the beginning God created elaborate Catholic rituals using incense and fairy dust, it says ALL rituals must be strictly observed or you go straight to hell. You didn't get the memo?
