Wow. I had not seen the Otechestvo, but yes that is disturbing on SO many levels.
Why do you find it disturbing, Anna?
Well, I am absolutely NO expert. I've only studied a limited number of icons. But ...
1. The biggest thing, by far, for me, is the positioning of "Joseph". I've never seen an icon of anyone but the Theotokos in this position with Christ, and it's so obviously similar. It just seems highly inappropriate.
2. The age of Joseph is far off. He appears to be a relatively young man, in contrast to all the teaching we have about him. It would undermine much other teaching about the Theotokos, and make her ever-virginity seem suspect, at best.
3. A minor point, but the resemblance between the two figures. The Joseph looks more like Christ - than Christ does. Somehow this seems to imply, on an unconscious level, that Joseph would be Jesus' biological father.
4. The dove - as mentioned - the whole Father-Son-dove iconography puts me in mind of the Trinity, and icons depicting the Trinity in this way are considered not canonical? Further, even if they were, putting Joseph in the position of God the Father is ... A problem, IMO.
Those are my main problems with it. But it's difficult for me to find something praiseworthy in it, in the face of all the issues it feels like it stirs in me.
Forgive me, I can be off in something. I'm just learning all this. And I hope nothing I've said is inadvertently offensive to anyone. But what I've gotten from Orthodoxy so far, makes me think of these issues.
