“The three Persons of The Holy Trinity: the Father, the Son, and the Holy Spirit come to us as long as we go to Them. They come with their help, if we come with our submission. They come with the intellectual light, if we want to learn something about God. They come to replenish our soul, if we want to be filled, provided that our vision of the Trinity be not from without but from within, and their indwelling in us be not fleeting but eternal.”
(St Augustine, Tract 76)
