Patrick Mugadza, 45, staged a demonstration at the ruling party, Zanu PF's, conference.
He held up a sign saying "Mr President, the people are suffering, Proverbs 21:13".
The verse reads: "Whoever shuts their ears to the cry of the poor will also cry out and not be answered."
Mr Mugadza is accused of "disrupting movement" by waving his sign about.
He has been freed on bail for trial in January.
Robert Mugabe has ruled Zimbabwe with an iron fist for 35 years.
The country has suffered years of rampant inflation and shortages of food and fuel.
