In the first, the individualistic, sense eschatology is an account of the destiny that awaits each person after death. In the second, the cosmic or social, sense it is a description of a goal (telos) in which history will be fulfilled. This goal may be either a this-worldly or an otherworldly kind. One of the important subjects of eschatology is the idea of a 'savior' to come at the end of time.
This awaited savior is known by various names and titles-Saoshyant, Messiah, Christ (in his Second Coming), and Mahdi, among many others. Since after the reign of King Solomon, the Jews have been waiting for the coming of a Messiah who, it is believed, would restore their lost glory and grandeur. Post-ascension of Jesus Christ is a period where the Christians have been longing for the second coming of Christ (Parousia).
The Muslims, on the other hand, have been expecting for the advent of Al-Mahdi (the Guided One) who, as a descendant of both Ishmael and Isaac, is believed to have been the epitome of fulfillment of the Abrahamic Covenant: "And when his Lord tested Abraham with certain words, and he fulfilled them, He said: 'I am making you the Imam of mankind.' Said he: 'And from among my descendants?' He said: 'My pledge does not extend to the unjust.'" (Surah al-Baqarah, 124) Neither is Filipino folklore devoid of it.
Legend tells us that Bernardo Carpio who is confined in a cave in Mt. Tapusi in Montalban Mountains (or Mt. San Mateo in Rizal) or trapped within two clashing mountains for a long time will one day come out to redeem the Philippines. (Ferdinand Marcos, as I was told by a Marcos loyalist when I was 12 during the 1986 Presidential Snap Election in the Philippines, was the personification of Bernardo!
First, every community holds that in the distant past it had a 'golden age' during which there was justice, peace, tranquility, and love, and that this golden age came to an end at some point in time and was followed by corruption, darkness and injustice. Secondly, they believe in a great and liberating upheaval in the future and a return to the golden age-the age of victory of justice, equality and brotherhood.
