I heard one priest describe Eucharistic Adoration as an extension of the adoration of the Blessed Sacrament at the consecration when the priests holds it up for all to see. The priest can’t stand there for hours and hours holding the Blessed Sacrament for us, so it is put into a monstrance where we can adore our Lord and spend time with him.
It is kind of sort of in the Bible. Ps 62 says: “So I gaze on You in the sanctuary, To see Your strength and Your glory” I always think of adoration when I read that, which is part of the Liturgy of the Hours on every Sunday and solemnity.
No other religions would have adoration as the Catholic church does because no other religion belives in the Real Presence. As mentioned, the Anglicans have a kind of adoration, but they say that if you believe in the Real Presence, it’s real, and if you don’t, its not real. Would drive me a bit nuts.
Adoration is very real and very powerful. Mother Teresa said that if every Catholic in the US would spend one hour per week in adoration, abortion would end. I think every Church should be required to have weekly adoration.
