Here's what you may be TEMPTED to do:
1) Write off the accusers as bitter. See this link for why that is most likely an unbiblical use of the term bitter.
2) Stick your head in the sand. If you do that, it's probably because you feel threatened. Perhaps you believed in that ministry and thought they were really good guys that had a new philosophy of ministry that would change the world. Maybe that pastor or ministry was a balm to you after a previous hard season as a Christian. Or maybe you came to the faith through that ministry. That can be really demoralizing. And if you don't have good, gospel-centered, Bible based tools to navigate that, your faith will likely feel threatened.
Here's some wisdom for navigating it.
1) If there is one allegation, listen carefully and weigh the evidence. But if there are many allegations, while you still need to listen and weigh, at some point, you need to face some truth from 2 Corinthians.
2 Corinthians 12:21-13:1 I fear that when I come again my God may humble me before you, and I may have to mourn over many of those who sinned earlier and have not repented of the impurity, sexual immorality, and sensuality that they have practiced. This is the third time I am coming to you. Every charge must be established by the evidence of two or three witnesses.Multiple witnesses establish credibility. In 2 Cor. 13:1, Paul quotes Deut. 19:15, so the truth he is presenting has long Biblical precedence. In God's recorded word, multiple witnesses establish credibility. You have to face that fact. Pardon the political reference, but this multiple witness thing is why I was always wary of the way things went down with Anita Hill and Clarence Thomas. There was no corroboration, but abusers usually don't stop with one abusive, harassing relationship (see Jerry Sandusky or Bob Packwood). If multiple similar accounts are coming out, then stop and consider, because the probability of serious problems goes up quickly with each new accuser. It is simply unbiblical to write off multiple accusers.
2) I wrote this week on the most needed peer pressure in Christianity, and that peer pressure to endure in love is definitely needed in such situations. Victims certainly need it, and I'm seriously hoping I don't need to give here all the Biblical reasons God expects us to defend and love those abused by authorities they trusted in their lives. The other issue is enduring with the accused. Enduring for the long haul with someone accused in such a situation does not mean you enable sin or excuse sin, but that you walk with them on their road of repentance and reparation. A lot of groups circle the wagons and dismiss accusers because the fear of acknowledging their sin, losing their reputation, and walking the long road of reparation overwhelms them. Other groups castigate the accused with ministries quickly severing the relationship with the accused, leaving them as a scapegoat to bear the weight of systemic problems.
But what if the accused had gospel loving friends who said, “I'll walk with you to the police precinct” (or where ever they may need to go to take the first steps of repenting and repairing). What if they had gospel loving friends who positively pressured them to repent and repair with the hope that such willingness to acknowledge their errors and the pain they caused would eventually lead to greater spiritual health for them and needed purification for their ministry.
THAT would be beautiful.
