Prayer has never been and never will be an act only reserved for Christians. It takes its form in almost every religious belief system on the earth.
While prayer is not unique to a religion or restricted, the problems arise with people misunderstanding prayers on behalf of others. (ie. Pr. Benke) In his specific religious sect he was praying not just for himself but for all the people in the stadium therefore speaking in the name of Christ for people who possibly did not believe.
Theologically and scripturally there is nothing strictly against this specific act, but as we are aware religious sects interpret scripture and meaning differently.
In this case you have people who are most likely looking at prayer as an earned rite for the believers.
For more specifics I would hope someone of that particular sect of christianity may help. But there is not canonical scriptural evidence backing the aforementioned actions in plain understanding of the text.
