His Omniscience

The concept of omniscience in relation to the Trinity refers to the belief each person of the Trinity — the Father, Son, and Holy Spirit — possesses complete and perfect knowledge. In Christian theology, omniscience means knowing everything: all things past, present and future, as well as all possibilities.

Here is a breakdown of how omniscience is understood within the Trinity:

1. The Father's Omniscience
The Father is universally accepted in Christian doctrine as omniscient. Scripture examples:

• "God is greater than our heart, and He knows everything." – 1 John 3:20
• "Great is our Lord, and abundant in power; His understanding is beyond measure." – Psalm 147:5

2. The Son's Omniscience
Jesus Christ, the Son, is also considered omniscient in His divine nature. However, during His incarnation, He voluntarily limited His use of some divine attributes (this is part of the doctrine called kenosis, from Philippians 2:6–8).

• Before resurrection: Jesus sometimes displayed limited knowledge, e.g.,
"But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father." – Mark 13:32
• After resurrection: Jesus is often seen as exercising full divine omniscience again, e.g.,
"Lord, you know everything; you know that I love you." – John 21:17
• In orthodox theology, this is not a denial of His divinity, but an expression of His humility in taking on human form.

3. The Holy Spirit's Omniscience
The Holy Spirit is also described as omniscient in Scripture. Since the Spirit is said to search even the deep things of God, He must know all.

• "The Spirit searches all things, even the deep things of God." – 1 Corinthians 2:10–11

4. Shared Omniscience Within the Trinity
Because the three persons of the Trinity share one divine essence, they also share attributes like omniscience. Meaning:

• There is no conflict or ignorance within the Trinity.
• Omniscience is perfectly united among the Father, Son and Holy Spirit.
• The economic roles (how they act in history and salvation) might differ, but the essential nature is shared.

Summary
Omniscience is a divine attribute shared fully by the Father, Son, and Holy Spirit. Apparent limits in knowledge (e.g., in Jesus' earthly ministry) are not denials of divinity but are explained theologically in terms of His incarnation. The Trinity operates in perfect unity of knowledge, will and purpose.
