Is there any reference regarding the use of these extra-biblical sources in Mennonite congregations?

**Background** A few years ago, a concern was raised by a member of a local Mennonite congregation about the use of citations from the Shepherd of Hermas . At the time, the concern was alleviated when it was mentioned that the Mennonite council endorsed its use as a secondary text. Recently, the concern was raised again. This time the member would like a citation or reference in order to substantiate either the endorsement, repudiation, or neutrality toward this text by Mennonite Bretheren. **Question** Does anyone have a cite or reference that discusses whether and to what extent the following extra-biblical sources are considered appropriate for teaching and instruction for Mennonite congregations? * Epistle of Barnabas, * The Shepherd of Hermas * The First Epistle of Clement to the Corinthians, Any citation or reference either supporting or repudiating these texts from a Mennonite denomination or organization is requested.
