No, there's nothing in the Constitution that even comes close to the phrase: "separation of church and state." Rather, it was a line used in a letter by President Thomas Jefferson in 1802. However, the SCOTUS has cited this phrase in decision making, and many people seem to agree with the concept. Similarly, speaking of Planned Parenthood, the phrase: "a woman's right to choose to abort a baby," is a creation of the SCOTUS, making it a 'law' bu judicial consent (activism?). Please don't read this and presume I'm a kool-aid drinking Trump supporter, but I am firmly pro-life; not based entirely based on my faith, but based on my belief that abortion is taking away the life of an innocent and helpless child.
