Filaret of Moscow, born Vasilij Michailovic Drozdov (1783-1867), served as the Metropolitan of Moscow from 1826 to 1867 and was one of the most significant Orthodox theologians of the 19th century. Controversial during his lifetime, he has been recognized as a saint by the Russian Orthodox Church since 1994. His shrine is currently located in the Cathedral of Christ the Savior in Moscow. The catechism commissioned by Tsar Alexander I was published in 1823 and reached its 33rd edition by 1833, with its final form established in 1839. After the catechism was translated into German in 1840, a new translation was published in 1872 by Dr. Heinrich Ludwig Johann Blumenthal (1804-1891), who was then the president of the Evangelical-Lutheran Consistory in Moscow. This translation serves as the basis for the present edition, which only adjusts the original text in terms of orthography, outdated word forms, and source references.
