Final answer:
Some communication made to members of the clergy is protected under Pennsylvania law based on the ruling in Murdock v. Pennsylvania (1943). The case established that the government cannot impose burdensome regulations on religious activities.
Step-by-step explanation:
Under Pennsylvania law, some communication made to members of the clergy is protected. In the case of Murdock v. Pennsylvania (1943), the Supreme Court ruled that a Pennsylvania ordinance imposing a license tax on those selling religious merchandise violated the Free Exercise Clause. This case established that the government cannot impose burdensome regulations on religious activities. However, it is important to note that not all communication to members of the clergy is protected under the law.
