Depends on what you mean by "how" and what you mean by "equal"
I meant it seriously, I was just trying to be humorous at the same time.
Your question is a little vague, if you could provide some details that would be great!
I believe Lossky touches on it here better than I:
The only characteristic of the hypostases which we can state to be exclusively proper to each, and which is never found in the others, by reason of their consubstantality, is thus the relation of origin. Nevertheless, this relation must be understood in an apophatic sense. It is above all a negation, showing us that the Father is neither the Son nor the Holy Spirit; that the Son is neither the Father nor the Spirit; that the Holy Spirit is neither the Father nor the Son. Otherwise to regard it would be to submit the Trinity to a category of Aristotelian logic, that of relation.Understood apophatically, the relation of origin describes the difference but nevertheless does not indicate the manner of the divine procession.
'The mode of generation and the mode of procession are incomprehensible,' says St. John Damascene.
'We have learned that there is a difference between generation and procession, but the nature of the difference we in no wise understand.' St. Gregory Nazianzen had already been forced to reject the attempts made to define the mode of the divine procession.
'You ask,' he says, 'what is the procession of the Holy Spirit? Do you tell me first what is the unbegottenness of the Father, and I will then explain to you the physiology of the generation of the Son, and the procession of the Spirit, and we shall both of us be stricken with madness for prying into the mystery of God.'Was it not this kind of prying with the Godhead which started the Arian Heresies elevating one person in degrees above or below another? I believe it should be avoided.
