Can someone be agnostic and Christian?

I 'm agnostic and I like progressive Christianity. Progressive Christianity is the name given to a movement within contemporary Christianity characterized by willingness to question tradition, acceptance of human diversity with a strong emphasis on social justice or care for the poor and the oppressed) and environmental stewardship of the Earth. Progressive Christians have a deep belief in the centrality of the instruction to "love one another" (John 15:17) within the teaching of Jesus Christ. This leads to a focus on compassion, promoting justice and mercy, tolerance, and working towards solving the societal problems of poverty, discrimination, and environmental issues
