Question: when did revelations become part of the bible

title: Book of Revelation
text: Christina Rossetti was a Victorian poet who believed the sensual excitement of the natural world found its meaningful purpose in death and in God . Her The Face of the Deep is a meditation upon the Apocalypse . In her view , what Revelation has to teach is patience . Patience is the closest to perfection the human condition allows . Her book , which is largely written in prose , frequently breaks into poetry or jubilation , much like Revelation itself . The relevance of John 's visions belongs to Christians of all times as a continuous present meditation . Such matters are eternal and outside of normal human reckoning . `` That winter which will be the death of Time has no promise of termination . Winter that returns not to spring ... -- who can bear it ? '' She dealt deftly with the vengeful aspects of John 's message . `` A few are charged to do judgment ; everyone without exception is charged to show mercy . '' Her conclusion is that Christians should see John as `` representative of all his brethren '' so they should `` hope as he hoped , love as he loved . ''
