"We thank Pastors Carl and Laura for the way they have served faithfully and sacrificially since the start of Hillsong NYC and for contributing so significantly to the countless lives that have been transformed for Jesus Christ through this ministry," the church's statement reads.
"They have a heart for people and we are confident that after a time of rest and restoration, God will use Carl in another way outside of Hillsong church. In terminating his tenure, we in no way want to diminish the good work he did here."
