== ''Expositio in Apocalypsin'' ==
Autpert's masterpiece is considered his ''Expositio in Apocalypsin'', a lengthy commentary on the [[Book of Revelation]]. Autpert refers to various [[early Christian writers]] in order to give his commentary authority. In addition, he uses the writers to correct heresy where he believed it to exist. Although he is very careful not to depart from the [[Sacred tradition|tradition of the Church]] or from orthodox teaching, his work is no mere string of patristic quotations. Throughout his Apocalypse commentary Christ is mystically identified with the Church, so much so that the Church actually begins with the birth of Christ. In addition, there is only one Church in heaven and on earth, not two. To those knowing the truth there is manifest one and the same Church, neither divided nor separated, which reigns with Christ in heaven, encompassing those members who have completed their struggle, and which reigns with Christ on earth, encompassing those members who continue in battle. The first resurrection (cf. Rev. 20:5b–6a), which implies a second, refers to the reign of Christ for a thousand years and the reign of the just with him. The second resurrection refers not to the resurrection of the flesh from dust but rather to the life of the soul rising from the abandonment of sin. The second death (cf. Rev. 20:6b) is eternal damnation. [[Gog and Magog]] (cf. Rev. 20:8) refer to the nations all over the earth which are agents of the devil persecuting the Church. The book of life (cf. Rev. 20:12) is the Old and New Testament, whose contemplation brings the elect to the light of day and the love of neighbour. The city of God continuously grows in number through the washing and regeneration of the [[Holy Spirit in Christianity|Holy Spirit]], and at the end of the present age the [[Last Judgment]] of God will come through his son Jesus Christ.
