Can Hobby Lobby have “sincerely held religious beliefs”?

A major point of the Hobby Lobby case is: “can Hobby Lobby claim the ACA exemption based on its “sincerely held religious beliefs”? 

In other words, can a for-profit corporation have “sincerely held religious beliefs”? If so - what - and who -  forms those beliefs?

I understand that a “covenant” was drawn up by the Greens. They claim that this covenant is anti-abortion, although it apparently allows abortion support in some places (their 401k's support companies who make abortion products, and China), and doesn’t allow support of “abortion” other places. If this covenant is their religion, then are we are basing “religion” on what people just write up - including what Muslims, Christian Scientists, Jehovah's Witnesses, and avowed anti-gay “religions” might write up? 

On the other hand, if the Bible is the religion, then are we really going to litigate the Bible in our courts?

And, if it is about how Hobby Lobby incorporates anti-abortion “religion” into their company,  then we must look at their actions, i.e., their support of abortion via their products from China and their taxes to China via their wholly-owned Chinese subsidiary, Hong Kong Connections Ltd,; the contributed funds towards the 401k’s (and probably the Green’s investment, as employees); and the fact that they supported the contraceptives before. These actions simply do not correlate with their “sincerely held” anti-abortion “religious beliefs”.

In other words, they are not walking the path of  their avowed “sincerely held religious beliefs”. Their path is profit - which is what a for-profit business should do.

What a corporation shouldn’t do, though, is be able to make up a religion and impose it on its employees. That is a precedent we simply don’t want - for the next “religious” corporation could easily have a religion few of us agree with.
