Thoroughly answer the given problem on Constitutional Law (Texas (US)) using the IRAC form.

PROBLEM:

In Texas state , there was a district judge who was notorious for his devotion as a Roman Catholic. Every day, he would attend mass and would pray countless times a day. He is also often seen wearing a rosary around his neck. Driven by his faith, one day, this judge urged a friend in the legislative to pass a state law directing courts to erect a cross at the front of the sala, just behind where the judge sits so that he may be guided by the Lord while he hears cases. Moreover, it was also dictated that every court hearing be preceded by a short prayer to invoke the guidance of God during the proceedings. Is the state law constitutional?
