UV/Baptism parallel

The UV that Snape takes has been compared to a wedding ceremony, with
Bella the Bonder as the officiating minister (except that she doesn't
speak, so the resemblance IMO is to a couple who speaks their own
vows). But it seems to me that there's also a resemblance to the
baptism of a child (or a baptism by proxy, if such a thing exists)
with Snape in the position of godparent, at least for the first two
provisions of the vow.

Narcissa: Will you, Severus, watch over my son, Draco, as he attempts
to fulfill the Dark Lord's wishes?

Snape: I will.

Narcissa: And will you, to the best of your ability, protect him from
harm?

Snape: I will.

Compare this excerpt from the Anglican liturgy for the baptism of a
(male) child:

Minister: Will you pray for this child, draw him by your example into
the community of faith and walk with him in the way of Christ?

Godparents: With the help of God, we will.
  	  	 
Minister: In baptism this child begins his journey in faith. You speak
for him today. Will you care for him, and help him to take his place
 	within the life and worship of Christ's Church?

Godparents: With the help of God, we will.

I realize that the parallels are not absolute, and that Narcissa is
asking Snape to watch over and protect Draco, but she is nevertheless
placing Snape (willynilly) in a position analogous to that of a
godfather as Draco begins his "journey" as a follower of the Dark
Lord, almost as if she expects Snape to act not only as Draco's
protector but as his guide in a dark imitation of the role
traditionally assigned to a godparent. At the same time, she's 
infantilizing Draco, placing him in the position of an infant or child
too young to speak his own vows.

In place of water and ritual cleansing, we have bonds of (hell)fire(in
seeming contradiction to the association of Slytherin with water and
Gryffindor with fire but consistent, perhaps, with devil worship.

I'm not discussing Snape's motives here, only the Darkness of the
magic and its distorted mirroring of the Christian liturgy. Does
anyone else see Snape in the role of godfather--or should I say
darklordfather--here? We already know that Snape is bound by ropes of
fire to keep his word or die. If this ritual is the antithesis of
Christian baptism (which provides for a child's protection and
guidance on his journey toward salvation), how would that add to our
understanding of Narcissa's expectations and Snape's predicament, as
well as his relationship with Draco?

Or maybe I'm reading in too much, and the significance is not in the
dark ritual but in the ropes of fire, symbolizing coercion and bondage
rather than free choice (and, of course, in the words themselves, the
vows that Snape is putting his life on the line by making).

Carol, certain that the UV is Dark magic and that Dumbledore would
never have bound Snape or anyone else to his will by compelling them
to obey him or die
