Augustine vs. Luther: Sexuality and Marriage

Augustine Versus Luther on Sin Sexuality and Salvation

Augustine and Luther agreed on many things, but the different ways they understood the first sin, its consequences, and its remedy continue to shape Protestant beliefs about sexuality and marriage.

Augustine and Luther’s diverging beliefs

For Augustine, in the late 300s and early 400s, the original sin of pride produced lust, which could be defeated through chastity. From him, the church inherited a sexuality shrouded in shame.

Luther saw original sin as unbelief, which led to pride—epitomized, in his view, by the Roman Catholic Church of the 1500s. For Luther, marriage was the remedy for self-righteous pride, and from him the church inherited an exaltation of marriage and sexuality.

Augustine fought personal issues stemming from his promiscuous pre-conversion lifestyle. His youthful lust drove him to find a lifetime of salvation in his relationship with Christ. He also battled two heretical groups and walked a tightrope of rhetoric. Forced to maintain the precarious balance between them, he didn’t pursue his theology far enough to reach an esteem for marriage and sexuality. [Read more…]

Born on May 10, 1886, Barth was trained as a pastor but schooled in German Protestant Liberalism. However his time as a pastor during the First World War caused him to reject his theological upbringing for a theology based upon God’s dialectical revelation. Barth first made a name for himself with his commentary The Epistle to the Romans, but it wasn’t until his unfinished 10,000-plus-page Church Dogmatics that Barth articulated the full breadth of his dogmatic vision.

Christ Is Risen! The Eastern Orthodox Celebration of Pascha

Easter (or “Pascha,” the Greek word for “Passover”) has yet to come for the Orthodox Church. While many Christians celebrated on March 31, a full five weeks separate the celebrations this year—Pascha takes place this Sunday, May 5. Let’s take a brief look at not only the history behind these differences, but also the manner in which Eastern Christians celebrate the Lord’s resurrection.

The dating of Easter has always been a complicated issue, going all the way back to the second century. At that time, the main divide was between those who celebrated on precisely the 14th day of Nisan (the Jewish Passover) and those who celebrated on the Sunday following the 14th of Nisan. This variance came to a head at the first Council of Nicaea (AD 325), when that assembly of bishops decided to regulate the celebration to always occur on a Sunday, or what had come to be called “the Day of the Lord” (Rev. 1:10).

A 19-year cycle of celestial calculations was developed, and this cycle, connected with the Julian calendar, has remained in use in the East. An 84-year cycle came to be used in the Western half of the empire, and so the first discrepancy (since the first Council of Nicaea) began to occur. With the assistance of the best astronomers and scientists of the time, Pope Gregory XIII revised the Julian calendar in 1582 in order to improve its accuracy. A reform of the Western lunar calendar—connected with the dating of Easter—also occurred. [Read more…]
