Calvin quotes Gergory of Nazianzus on the threeness of the Trinity:
“I cannot think on the one without quickly being encircled by the splendor of the three; nor can I discern the three without being straightway carried back to the one.” Calvin continues in his own words, “Let us not, then, be led ot imagine a trinity of persons that keeps our thoughts distracted and does not at once lead them back to that unity. Indeed, the words ‘Father,’ ‘Son,’ and ‘Spirit’ imply a real distinction – let no one think that these titles, whereby God is variously designated in from his works, are empty-but a distinction, not a division.” (1.8.17)
Calvin takes a balanced approach to the Trinity – keeping a solid base on the revelation of Scripture in regards to the Trinity. Calvin was impressed with the importance of keeping a clear understanding of unity of essence but also in that not disregarding the distinction of Father, Son, and Spirit.
Calvin writes, “Therefore, let those who dearly love soberness, and who will be content with the measure of faith, receive in brief form what is useful to know: namely, that, when we profess to believe in one God, under the name is understood a single, simple essence, in which we comprehend three persons, or hypostases.” (1.8.20)
It seems best for us to steer clear of distractions in considering the Trinity and stick to what has been revealed.
