Lex Orandi, Lex Credendi, Lex Vivendi
This Latin phrase (as we worship, so we believe, so we live) typifies the importance of 
worship and liturgy in the life of the Church. It is with this importance in mind that the Church offers the following resources to its clergy.
It is hoped that these resources will assist you all in offering worship to the faithful that brings all the faithful into closer union with God.
Please note these resources are not in any way binding or express the official opinions of the Church, unless stipulated in Canon Law. For matters of policy, procedure or doctrine please consult the Canons of the Unified Old Catholic Church or the Office of the Presiding Bishop.
