18 No man hath seen God at any time: the only begotten Son who is in the bosom of the Father, he hath declared him.
This doctrine needs to be reiterated from the pulpit in these times when there is so much confusion concerning the Trinity. This reference indicates that no man has ever seen the Father, even in these times, that is the New Testament times in which we live.
Christ has seen the Father and reveals the Father to us. Christ is the only Person of the Blessed Trinity Who is Incarnated, Who can be seen as a Man, as He is Man.
Many artists, including the great Michelangelo, have depicted the Father, either as an old man, as a creator, or in symbols, such as one member of the Trinity.
In the Church today, some people are confused about the Person of the God the Father.
When the Trinity appeared to Abraham, the Three Persons were seen as angels, that is as spirits, not as men.
And, when God passed by Moses on Sinai, and Moses only saw His Back, we do not know if that was not Christ, rather than God the Father. To see God as a Human, with human characteristics, that is a body, indicates that this revelation could have been one of Christ, Who although became Man at one moment of time and chose to be bound by time, could have revealed Himself. Christ, after His Resurrection was seen by many people, of course. To speak of the Face of God and the Back of God are human terms, not spiritual ones. The spiritual meaning of these is doubtful. We do not know what these mean.
God can imprint an image on our imagination to help us understand Him, but this image is not necessarily Him. Only Christ is the Image of the Father,
The vision of Ezechiel of God seems to be more accurate, as it is mysterious.
Even the Navajos have a myth of a non-Native appearing to their ancestors over a thousand years ago, as shown in an ancient cave painting. This revelation was of Christ, not the Father.
God the Father is a Spirit, not a material being. Christ is both. The Holy Spirit is, obviously, a Spirit.
All three Persons in the Trinity are one but unique. We cannot imagine the Father without the revelation of the Son.
