Anti-persecution charity Christian Solidarity Worldwide (CSW) is concerned about the severity of the charges brought against Rev Yat Michael and Rev Peter Reith.
Both pastors, from the Presbyterian Evangelical Church, have been accused of undermining the constitutional system of the Sudanese Penal Code; waging war against the state; disclosure and receipt of official information or documents; arousing feelings of discontent among regular forces; breach of public peace; and offences relating to insulting religious beliefs.
The charges can carry the death sentence, or life imprisonment.
Both men appeared in court on May 19th, where evidence was presented against them.
The Africa Advocacy Officer at CSW, who cannot be named for security reasons, told Premier that some of the evidence used seemed to come from secret recordings: "This was a speech that was given in a church service and NISS (National Intelligence and Security Services) were essentially monitoring and recording the events going on in the church.
"So this is really a concern of the wider picture of what's going on in Sudan for Christians."
She added that the government are targeting church buildings in particular and are refusing to issue any more licences: "No new licences will be issued, which means churches will have no place to meet, which means that Christians can't exercise their full right of freedom of religion or belief by meeting together."
The men will appear in court next on May 31st.
CSW said the severe charges levelled against them are the latest development in a series of repressive official actions targeting Christians in Sudan, a predominately Muslim country.
