Yes, but the Father has no bodily shape or form; the heavens and the heavens of the heavens cannot contain Him, (Deut 10:14, 1 Kgs 8:27, 2 Chr 2:6, 2 Chr 6:18), so imagine a white dove descending from the heavens or the sky in somatikos-bodily form: the dove itself has a bodily shape or form, (somatiko, Luke 3:22, and likewise this terminology is used of Messiah in Col 2:9). In the mind, (singular), of the authors, (plural), there is no way they thought of Messiah as being equal to the Father: for they knew the scripture, and the Father is non-corporeal Spirit. The Father has no shape or form whatsoever because any shape or form of His own self would by definition contain Him. The dove is not equal to the sky as it descends because it descends within the confines of its own body with the backdrop of the heavens or sky around it. Likewise the sky itself containing the dove is still not equal to the Father; for all things of creation are within the Father who is over and above all. We breathe His air, we swim in His waters, we fly in airplanes through the midst of His sky; and yet He is still greater than all these things. Look at your image file and imagine a dove just the same; either way it is a bodily shape or form and cannot contain the Father, although the Father may be in and through the form, (being greater than the form and being all in all in all things holy). If Messiah is even remotely likened to a phantasma traversing across the water then the author of that text in no way thinks of him as "equal to the Father" because he writes that they saw some sort of a bodily form, (of light), coming toward them over-upon the water. Messiah is the embodiment of the Word of the Father and the Word of the Father can be, and is, localized anywhere and everywhere for different and varying purposes. In essence Messiah is the perfect image-stamp of the Father; His perfect vessel; His physical extension into the world, His right arm of salvation, whom we are to emulate and become by way of his Testimony which he received from the heavens and apportioned to his disciples, apostles, and brethren. By that very Testimony, (if we hear, observe, and maintain it), Messiah Yeshua is the Mediator between the Father and His people.
