No matter what deficiencies we see in the man, his pastor saw fit to send a letter of recommendation to the Bishop on his behalf, he went through and passed a very thourough psychiatric examination, spent several years in formation, and if he is married, his wife went through a rigourous process as well. At the end of the day, the bishop saw something in the man and decided that he would be a deacon.
The truth is that what you see a deacon doing at Mass is an extremely small portion of what a deacon really does. Let’s face it, an altar server could do what a deacon does. Deacons are ordained into service, and they are engaged in ministry outside the parish, even ouside the Catholic Church - prison ministry, working with the poor, hospital ministry, hospice, Habitat for Humanity, Alcoholics Anonymous, etc. I know a deacon who helps people pick out caskets and burial plots for family members who just died. He walks with them into the morgue or funeral home to identify the body.
What you see a deacon doing at the altar is about 5% of what a deacon does. Liturgy is a small part of who a deacon is. If you get a chance, strike up a conversation with a deacon and ask him what his ministry is. You might be surpised.
At the end of the day, the man was called by God, and that call was confirmed by the bishop, and there is little we can do about that.
