*deep breath* Okay, so this is complicated, but the short answer is... in some ways, yes, in other ways, no. They have some theological differences, and organizational differences, but they're quite similar in other ways.

(And technically they recognize the pope as a fellow bishop (the Bishop of Rome), and as the leader of the Roman church, but NOT as the leader of the Episcopal church/Church of England. See Primus Inter Pares.)

(And if you really wanna break your brain, hardcore technically Episcopals are both Catholics AND Protestants. When you say "Catholic" you're probably referring to "Roman Catholic" but there's more than just the Roman church and the word "Catholic" (with a capital C) has a specific meaning and encompasses a number of different churches.)
