However, Judeo-Christian thought also makes an "innovation of the first importance", Eliade says, because it embraces the notion of linear, historical time; in Christianity, "time is no longer the circular Time of the Eternal Return; it has become linear and irreversible Time". Summarizing Eliade's statements on this subject, Eric Rust writes, "A new religious structure became available. In the Judaeo-Christian religions—Judaism, Christianity, Islam—history is taken seriously, and linear time is accepted. [... The Christian myth gives such time a beginning in creation, a center in the Christ-event, and an end in the final consummation."
