Prior to 1960, yes, but not so much a sin as a "scandal". This is certainly no longer the case.
Roman Catholic AnswerTo clarify the answer above. Yes, it always involved the sin of scandal (among other things) and, yes, it is still a sin. You may attend an Ecumenical service for a good reason, or, perhaps, the baptism of a friend of relative who is not Catholic, however, it is still a sin to actively particiate in such a service in any way as that would be supporting a schismatic or heretical sect. If you feel a need to attend such a service for a good reason, I would recommend asking your pastor about this. Contrary to the above answer it is still the case, just not quite as black and white as it was before.It was a Protestant service - Church of England or Anglican.

No.AnswerIf you mean 'catholic' with a small 'c', then yes. the word 'catholic' simply means 'universal' and so the Protestant Church is part of the universal Christian Church worldwide. If you mean 'Catholic' with a large 'C' - this usually refers to the Roman Catholic Church and, though the Protestant Church is part of the catholic (universal) church, it is not part of the Catholic (Roman Cattholic) church as this is a separate denomination.
The first Protestant denomination that emerged after the Catholic Church was the Lutheran Church, which was founded by Martin Luther in the early 16th century. Luther's teachings and his criticism of certain practices of the Catholic Church led to the Reformation and the establishment of the Lutheran Church.
There is no "Roman" Catholic Church: Roman is an epithet first commonly used in England after the protestant revolt to describe the Catholic Church. It is rarely used by the Catholic Church. The Chaldean Catholic Church is part of the Catholic Church.
.Roman Catholic AnswerOnly one: the Catholic Church was the only Church involved in the protestant revolt when the "protestants" left the Church.
The Protestant Church emerged out of the Reformation of the Catholic Chruch
No, however, the church in England was Catholic up until the protestant revolt in the sixteenth century when the Church of England was created.
The Church of England in and of itself is a Protestant church. It split from the Catholic Church around 1526 under Henry VIII.
Roman Catholic AnswerNo one, the Catholic Church cannot be "combined" with anything. The Anglican Church is a protestant church that was formed by Henry VIII as he left the Catholic Church and then it was established by Parliament under his daughter, Elizabeth I.
