This is not the work of A Collection of Prayers, but a very useful and amazing project.
Someone has researched and compiled Scripture references behind every rite and prayer in The Book of Common Prayer. Here is their preface:
The Book of Common Prayer (BCP) is a landmark document of the Anglican tradition and the English language. Its unique rites, formulations, and collects are suffused with Biblical quotation and allusion.
This resource is a port of The Book of Common Prayer: With marginal references to texts in the Holy Scriptures published by the Church of England in 1839 (archive.org link), which aims to catalogue each scriptural reference in the text of the 1662 BCP.
Inline Biblical quotations are taken from the New Revised Standard Version (BibleGateway link).
And here is the link to The Scriptural BCP.
