With respect, what other, philanthropic organisations do is not the point. If their contitutions allow these activities then ok, no problem for them. If an organisation's contitution states that it is non demoninational, then it is obliged to act accordingly.

Engaging in religeous activities is not part the organisation's stated aims. Taking funding from from other bodies who are not allowed to fund religeous activities is just, plainly and simply, wrong no matter how well intentioned.

The constitution may be viewed here. Kindly check clause 3. :-)
