English please. Are you saying nobody in your church pictures Jesus in their mind when they pray or praise Him?

If they do this it is simply due to ignorance on their part as the use of the visual imagination during prayer is emphatically discouraged in the vast amount of Orthodox literature on the subject, as being potentially inductive to various forms of demonic delusion.
The Philokalia, a collection of ascetic treatises on prayer that is essentially unsurpassed in its splendour, and which spans a period from the late fourth through I believe the seventeenth century (volume 5 alas has not yet been translated into English, also there is a slightly different Romanian edition), spends a fair amount of time on this issue.
One included treatise is from St. Symeon the New Theologian, on the Three Methods of Prayer:
"The distinctive features of the first method of prayer are these. When a person stands at prayer, he raises hands, eyes and intellect heavenwards, and fills his intellect with divine thoughts, with images of celestial beauty, of the angelic hosts, of the abodes of the righteous. In brief, at the time of prayer he assembles in his intellect all that he has heard from Holy Scripture and so rouses his soul to divine longing as he gazes towards heaven, and sometimes he sheds tears. But when someone prays in this way, without him realizing it his heart grows proud and exalted, and he regards what is happening to him as the effect of divine grace and entreats God to allow him always to be engaged in this activity. Such assumptions, however, are signs of delusion, because the good is not good when it is not done in the right way.
"If, then, such a person is pursuing a life of stillness and seclusion, he will almost inevitably become deranged. And even if this does not happen to him, it will be impossible for him to attain a state of holiness or dispassion. Those who adopt this method of prayer have also been deluded into thinking that they see lights with their bodily eyes, smell sweet scents, hear voices, and so on. Some have become completely possessed by demons and wander from place to place in their madness. Others fail to recognize the devil when he transforms himself into an angel of light (cf. 2 Cor. 11:14); and, putting their trust in him, they continue in an incorrigible state of delusion until their death, refusing to accept the counsel of anyone else. Still others, incited by the devil, have committed suicide, throwing themselves over a precipice or hanging themselves.
"Indeed, who can describe all the various forms of deception employed by the devil? Yet from what we have said any sane person can understand the kind of harm that may result from this first method of attentiveness. Even if someone who has adopted this method may perhaps avoid the evils we have mentioned because he lives in a community - for it is solitaries who are especially subject to them - none the less he will pass his entire life without making any progress. "
So when we cross reference this text from St. Symeon, the most recent person to be honored as a Theologian, e.g. one wih experiential knowledge of God (the other two being St. John the Beloved Disciple and St. Gregory Nazianzus) by the Eastern Orthodox Church, with the anathemas at the Second Council of Nicea against those who worshipped or accused the Churc of worshipping icons as gods, we see compelling reason to reject as calumny the proposition that the Orthodox are in any sense idolaters.
