关于神圣的三一，有两个主要的方面，就是素质的三一与经纶的三一。素质的三一指三一神的素质，是为着祂的存在。经纶的三一乃指祂的计划，是为着祂的行动。
在素质三一的方面，父、子、灵是同等、同时的并存，互相内在，没有先后之分；也没有第一、第二、或第三的分别。
然而，在神的计划、神的行政安排、神的经纶里，却是父采取第一步，子采取第二步，灵采取第三步。父计划，子完成，灵应用子照父的计划所完成的。这是神经纶里的先后次序，以达成祂永远的目的。
素质的三一乃指三一神的素质，是为着祂的存在；经纶的三一乃指祂的计划，是为着祂的行动。有神圣三一存在的必要，也有神圣三一计划的必要。
Concerning the divine trinity, there are two main aspects: the essential trinity and the economical trinity. The essential trinity refers to the essence of the Triune God for his existence. The economical Trinity refers to his plan for his move. There is a need for the existence of the Holy Trinity and a need for the plan of the Holy Trinity.
In terms of the essential Trinity, the Father, the Son and the Spirit are equal, co-existing and mutual immanence; there is no distinction of first, second or third.
However, in God’s plan, God’s administrative arrangement and God’s economy, it is the Father who takes the first step, the Son who takes the second step, and the Spirit who takes the third step. The Father planned and the Son accomplished, and the Spirit applies what the Son has accomplished according to the Father’s plan. This is the sequence in God’s economy for the fulfillment of his eternal purpose.
