The English-language text of Christ our Pascha, the official catechism of the Ukrainian Catholic Church, is now available online! You can view the text on the Royal Doors website here.
Royal Doors has also made available a number of resources to accompany the catechism which you can find on their website.
The text is also available on the Catechism tab of this website. There you may also find the link to purchase a hard-copy of the catechism (highly recommended!).
