Could you provide a Scriptural reference for that description?
Sure. The 12th chapter of Revelation. And the verse immediately preceding it (Rev 11:19) which refers to the ark of the covenant, which is the Catholic view of Mary. The 12th chapter shows us Mary as mother of Christ and symbol of the church. We see her crowned as queen mother (1 Kg 2:19) of the royal son (Ps 2:9; Hb 1:8). We read in the last verse that she is mother of all who keep God's commandments and bear testimony to Jesus.
