This statement accurately reflects the traditional Christian doctrine of the Trinity. Here's a breakdown:
* Second Member of the Trinity: Yes, Jesus Christ is traditionally understood to be the second person of the Trinity.
* Equal with the Father in Nature (or Essence): This is a core tenet. The Father, Son (Jesus Christ), and Holy Spirit share the same divine nature, substance, or essence. They are all fully God.
* Submissive in Duty (or Role, or Economy): While equal in divinity, the Son is understood to have a subordinate role or function within the Trinity, particularly in the context of salvation history. This is often referred to as the "economic Trinity" (how God relates to the world). Jesus, in his incarnation, willingly submitted to the Father's will.
Therefore, the statement is true according to traditional Christian theology.
