An ecumenical event will take place at the National Mall in Washington, D.C. on July 16 that will bring together Evangelical and Catholic speakers and musicians.

"Together 2016" will feature Hillsong United, Lecrae, Crowder, Kari Jobe, Andy Mineo and others to "ask Jesus to reset our generation."

According to organiser Nick Hall of Pulse, "Together 2016 is about laying aside what divides us to lift up Jesus who unites us. We are coming together in historic unity to pray for a reset for our nation."

"Jesus said that His followers are family. We believe that it is time for a family gathering," he added, according to the Christian News Network. "It's not about what divides us, but about the one who unites us—Jesus. The world sees division. We can change that."

Pope Francis will be delivering a video message to the thousands who are expected to attend the event.

"We've been praying for this and God has been answering our prayers," Hall said, adding that he and the Pope will pray together on Friday.

But some are concerned about Christians and Catholics coming together because of Gospel differences.

"Nick Hall either does not know the exclusivity of the Gospel of God or he does not know the Roman Catholic plan of salvation because they are diametrically opposed," said Mike Gendron of Proclaiming the Gospel Ministries who was a former Catholic.

He cited the differences between Christians and Catholics when it comes to the Gospel.

"We're divided on how one is born again: Rome says water baptism; the Bible says the work of the Spirit. We're divided on how one is justified: Rome says faith plus works, the Bible says faith. We're divided on how one is purified of sin: Rome says purgatory, the Bible says the blood of Jesus. We're divided on the essentials of the Gospel: Rome has other mediators, the Bible says it's Christ alone," he said.

"Together 2016" has earned the support of many including The Billy Graham Evangelistic Association, the Luis Palau Association, CRU (formerly Campus Crusade for Christ), Intervarsity Christian Fellowship, Premiere Productions, the National Day of Prayer, YWAM and the American Bible Society.

Joel Houston of Hillsong United said he loves the name "Together."

"There's a power in unity and a blessing that comes when people put aside their differences and gather together for one purpose. Our prayer is for this to be a reset for us as a generation of the Church—in America and beyond," he said.
