Problem
Give a detailed understanding of this Scripture verse in light of two significant Christian doctrines (e.g. Trinity, Incarnation, creation in the image of God, Sacraments and Liturgy):
Hear, O Israel! The LORD is our God, the LORD alone! Therefore, you shall love the LORD, your God, with all your heart, and with all your soul, and with all your strength. Take to heart these words which I enjoin on you today. Drill them into your children. Speak of them at home and abroad, whether you are busy or at rest. Bind them at your wrist as a sign and let them be as a pendant on your forehead. Write them on the doorposts of your houses and on your gates. (Dt 6:4-9 (NAB))
