Do Not Go Beyond What is Written!
“Let us use great caution that neither our thoughts nor our speech go beyond the limits to which the Word of God itself extends.” Institutes, 1.3.21.
“Let us not take it into our heads either to seek out God anywhere else than in His Sacred Word, or to think anything about Him that is not prompted by His Word, or to speak anything that is not taken from that Word.” Institutes, 1.3.21.
