The Concept of God’s Oneness in Mark 12:29

Muslims argue that Jesus taught tawhid, referring to what he said in Mark 12:29. Is this what Jesus meant “tawhid”? In fact, Jesus responds to a scribe who asks Him which commandment is the most important. Jesus replies by quoting the Shema from Deuteronomy 6:4-5: “Hear, O Israel: The LORD our God, the LORD is one. Love the LORD your God with all your heart and with all your soul and with all your strength.” This passage, central to the Jewish faith, emphasizes God’s oneness, a fundamental monotheism tenet.

The Term “Echad” in the Shema (Deuteronomy 6:4):

The Hebrew word translated as “one” in this verse is “Echad” (אֶחָד). “Echad” often denotes a composite unity rather than an absolute singularity. This is evident in various contexts throughout the Hebrew Scriptures:

1.   Genesis 1:5 – “And there was evening, and there was morning—the first (Echad) day.” Here, “Echad” describes a day that consists of two distinct parts, evening and morning, yet is considered one.

2.   Genesis 2:24 – “Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one (Echad) flesh.” In this context, “Echad” refers to the union of two distinct individuals, a husband and wife, into a single entity in marriage. This usage of “Echad” clearly implies a unified plurality.

3.   Exodus 24:3 – “So Moses came and told the people all the words of the LORD and all the judgments. And all the people answered with one (Echad) voice and said, ‘All the words which the LORD has said we will do.’” Here, “Echad” is used to describe the unified response of a multitude, again suggesting a collective unity.

Given these examples, “Echad” in Deuteronomy 6:4 does not necessarily imply a singular, indivisible entity but can encompass a unified complexity, which is consistent with the Christian understanding of the Trinity—three distinct Persons (Father, Son, and Holy Spirit) who are one God.

Contrast with “Yachid”:

The Hebrew language has another word, “Yachid” (יָחִיד), which conveys the idea of absolute singularity or uniqueness. It is used in contexts where an emphasis on exclusivity or individuality is needed:

1.   Genesis 22:2 – “Then God said, ‘Take now your son, your only (Yachid) son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you.’” Here, “Yachid” describes Isaac as Abraham’s only son, emphasizing his unique status.

2.   Psalm 22:20 – “Deliver my soul from the sword; my darling from the power of the dog.” The term “darling” here is “Yachid,” signifying something singular and cherished.

If the Shema was intended to express an absolute singularity of God, “Yachid” could have been employed. Instead, the choice of “Echad” allows for a theological understanding of God’s unity that is compatible with the Christian doctrine of the Trinity.

The New Testament Perspective on God’s Oneness:

The New Testament affirms the oneness of God while revealing the complexity of His nature:

1.   Matthew 28:19 – “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” This verse, part of the Great Commission, explicitly identifies the three distinct Persons of the Trinity within the single “name” (authority) of God.

2.   John 10:30 – Jesus says, “I and the Father are one.” The Greek word for “one” here is “hen” (ἕν), indicating unity of essence or nature, not merely agreement in purpose. This statement aligns with understanding “Echad” as a unity of multiple persons.

3.   2 Corinthians 13:14 – “The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Spirit be with you all.” Paul’s benediction encapsulates the triune nature of God, referencing the three distinct Persons who together form the one God.

4.   Ephesians 4:4-6 – “There is one body and one Spirit, just as you were called to one hope when you were called; one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all.” Paul emphasizes God’s oneness while referencing the distinct roles of the Spirit, the Lord (Jesus), and the Father.

Theological Implications:

The Christian doctrine of the Trinity, though not explicitly stated in a single verse, is derived from the comprehensive testimony of Scripture, both Old and New Testaments. The Shema’s declaration of God as “Echad” is understood in this light to affirm that God is one in essence yet revealed in three distinct Persons. This concept is not a contradiction of monotheism but a fuller revelation of the complex unity that “Echad” accommodates.

Conclusion: In Mark 12:29, when Jesus quotes the Shema, He reaffirms the foundational Jewish belief in one God. However, by using the term “Echad” (as found in Deuteronomy 6:4), the Scripture leaves room for the later revelation of God’s triune nature—a singular and composite unity. The Christian interpretation thus harmonizes the Old Testament affirmation of God’s oneness with the New Testament revelation of the Trinity.
