Great advice Eric… get involved with your church if you are not already.
Some other areas that you may want to get involved in are outside of the mass though. Much of a Deacon’s life is spent outside the physical church and in the community. Reach out to the needy… help out with Jail ministry. This is a great experience as many of these men and women are arching and thirsting for Jesus. Most dioceses will have an office that will assist you with this and will pair you up with someone who has been doing this for some time.
Volunteering at a soup kitchen or homeless shelter is also another great opportunity. It get’s you working with those who need help and that is what the Church is all about. On many Thursday’s I will volunteer at a local Soup kitchen and I love doing it.
If you are an Eucharistic minister, you could also take communion to the jails on Sunday’s (or to nursing homes or shut in’s). If you are not an Eucharistic minister, what are you waiting for? Talk with your pastor and find out when the next training session is. I love distributing communion!
You can also be a lector and read the readings. As a Deacon, you will have to proclaim the word of God, so now is a great time to get yourself comfortable of standing up and reading the readings. I know 10+ years ago when I started to do this it terrified me, but now I have no concerns and love doing it.
Another option is to teach PSR or help with the RCIA program. Both are great opportunities to develop teaching skills which you may need as a deacon.
The key is get involved (inside the physical church and outside of it). Social outreach is big as there are may marginalized people out there and one of the roles of the Deacon is to be a servant, just like Jesus was.
Anyhow, when I first approached the diaconate, they commended me on how I helped with readings and as a Eucharistic minister, and in doing the Liturgy of the Hours, but they said that is just a small part of what a deacon does and they encouraged me to start doing the social outreach items too, to help balance that all out.
Lastly, If you do not have a spiritual director I would recommend that you obtain one to assist you with your discernment and your spiritual life in general.
