In 2011 Diaconal Ministries Canada (DMC) produced twelve devotions for deacons intended for use at monthly deacon meetings. Apparently the positive response to these devotions was such that DMC is now producing a second set of devotions for deacons which they will be releasing on a monthly basis. The first devotion in this series was posted to their website blog in early June which you can access and download at this link. Each of the new devotions will be available in a package with additional resources and discussion questions. Alternatively, you may choose to simply download the devotion without the accompanying material. (You can go to this link to see the difference for yourself)
The DMC website (diaconalministries.com) has a wealth of information and resources for deacons and diaconal ministries of the church. Additionally, the materials and information I have viewed and read are relevant and useful for deacons in nearly any setting. I have also found their information and material to be "in step" with and reflective of the changes that are occurring . . . especially as it relates to the Office of Deacon in the CRCNA. Take some time to look around and see if there is something that might be helpful for you or your diaconate.
