The Church teaches that there is only one God Who is the creator. Everything else is a creature or creation. That one God is the God of Abraham and all monotheistic belief systems derived from it, regardless of the degree of error, are worshiping the one God. That applies equally to our separated brothers and sisters, who err to a lesser degree, such as Baptists, Calvinists, Lutherans, and free-range Evangelicals such as the Calvary Chapelists.
Peace be with you
