So, my son attends school at the church

[proffesor] ok, so "trix". Why the peculiar spelling of tricks? The "x" is important. Let's remove it and place it at the beginning: "Xtri" aka "christri". Now lets remove the second "r" because it doesn't fit what I want to believe: "christi". So if we follow through with our eyes, we see "Christi" and a "t" >>> "Christi and a t" >>> "Christiandat" >>> "Christianity"... WAKE UP! [/professor]

But anyway beyond that, the letter T looks nothing like a cross, the word trix isn't a word that I know of, so I'd say looking at it on face value it's a very useless lesson with no value.  And yes that does look a lot more like a religious symbol than a letter so you're probably not just being paranoid.

Uh, guys. Trix is the name of a kid's cereal. The same cereal that is glued to the LETTER "t" on the OP's picture.

And who was trying to get the Trix?

That's right . . . the silly rabbit.

And who else was a silly rabbit?

Could it be . . . the Easter Bunny?

And what other fictional character is famous for Easter?

That's right . . . Christ!   

They're probably doing this thing where each day they learn a letter and have to glue things to it that begin with that letter. 

Yes, the letter "t" . . . as in THE SON OF GOD!!!

Of course, it's a silly tempest in a teapot. If they were depicting the cross, the red Trix pieces would have gone at the head, the arms, and near the bottom, where God intended.
