(a) The principal of Jaena High School, a public school wrote a letter to the parents and guardians of all the school's pupils, informing them that the school was willing to provide religious instruction to its Catholic students during class hours, through a Catholic priest. However, students who wished to avail of such religious instruction needed to secure the consent of their parents and guardians in writing. Does the offer violate the constitutional prohibition againts the establishment of religion? (b) the parents of evangelical Christian students, upon learning of the offer, demanded that they too be entitled to have their children instructed in their own religious faith during class hours. The principal, a devout Catholic, rejected the request. As counsel for the parents of the evangelical students, how would you argue in support of their position?
