Sunday is Trinity Sunday (First Sunday after Pentecost). It is an appropriote time to look at the dynamic between the Father, Son, and Holy Spirit. It is a dynamic that is important to the doctrine and heart beat of the Church.
*Let us live in this love and this happiness, you and I and all of us, in the love of Christ and in contemplation, for this is where we find ourselves and one another as we truly are. It is only in this love that we at last become real. For it is here that we most truly share the life of One God in Three Persons.
*God in His Trinity of subsistent relations infinitely transcends every shadow of selfishness. For the One God does not subsist apart and alone in His Nature. He subsists as Father and as Son and as Holy Spirit. These Three Persons are one, but apart from them God does not also subsist as One. He is not Three Persons, plus one nature therefore four! He is Three Persons but One God. He is at once infinite solitude (one nature) and perfect society (three persons). One infinite Love in three subsistent relations.
The One God Who exists only in Three Persons is a circle of relations in which His infinite reality, Love, is ever identical and ever renewed, always perfect and always total, always beginning and never ending, absolute, everlasting and full.
In the Father the infinite Love of God is always beginning and in the Son it is always full and in the Holy Spirit it is perefect and it is renewed and never ceases to rest in its everlasting source. But if you follow Love forward and backward from Person to Person, you can never track it to a stop, you can never corner it and hold it down and fix it to one of the Persons as if He could appropriate to Himself te fruit of the love of the others. For the One Love of the Three Persons is an infinetly rich giving of Itself which never ends and is never taken, but is always perfectly given, only received in order to be perfectly shared.
It is because the Love of God does not terminate in one self-sufficent self that is capable of halting and absorbing it, that the Life and Happiness of God are absolutely infinite and perfect and inexhaustible. Therefore in God there can be no selfishness, because the Three Selves of God are Three subsistent relations of selflessness, overflowing and superabounding in joy in the Gift of their One Life.
The interior life of God is perfect contemplation. Our joy and our life are destined to be nothing but a participation in the Life that is theirs. In Them we will one day live entirely in God and in one another as the Persons of god live in One another.
As Christ says ‘I in them and Father, You in me, that they may be made perfect in One…and the glory which you have given me I have given to them, that they may be One as we are One’ and ‘In this shall everyone know you are my disciples—if you have love for one another.’
