Why do you want to go?
Attending a non-Catholic service does not fulfill your Sunday obligation. If you are going to display a kind of ecumenism, I wouldn’t advise it as you are saying, in effect, that all churches are the same—this is false ecumenism. If you are going because it is the church your spouse goes to and you wish to maintain family unity, then that’s OK (as long as you still go to Mass at a Catholic Church in order to fulfill your obligation).
