Catechismus in der windischenn Sprach

Catechismus in der windischenn Sprach or simply Catechismus (Catechism, also known as Katekizem v slovenskem jeziku or simply Katekizem in modern Slovene), is a book written by the Slovene Protestant preacher Primož Trubar in 1550.

[1] Catechismus served as part of a foundation of the establishment of a national identity for Slovenes.

Based on the German patterns, they are original poems in four different forms of stanzas comprising altogether 500 verses.

The "Pridiga o veri" (Sermon on Faith) from Catechismus is available in Slovene, English, German, and Esperanto.

A phrase from Cathecismus, Stati inu Obstati ("To Stand and Withstand"),[5] is inscribed on the Slovenian 1 euro coin and has also been the slogan of the former Slovenian metropolitan archbishop Franc Rode.
