The Reformations fundamental alterations to traditional forms of church service, had, by Bach"s time, resulted in German churches Latin yielding to the country"s own language. To a limited extent, however, the Latin mass text did remain in use in the Protestant church in particular the Kyrie and Gloria sections. Termed Missa to differentiate them from complete settings, these pieces are often referred to now as "Lutheran Masses". Bach"s famous Mass in B minor began its existence as a work of this type, and four other examples from Bach"s pen have survived. Newly performed and recorded by Bach Collegium Japan under the direction of Masaaki Suzuki, the Missae BWV 235 and 236 are here combined with four separate settings of the Sanctus. Two of these are original works, whereas BWV 241, and possibly also 240, is an arrangement of another composers setting. The "KyrieChriste" BWV Anh 26 is an example of how Bach used music by other composers, in this case by his Neapolitan contemporary Francesco Durante.
