The following is an excerpt from WIKIPEDIA:
Reformed confessions of faith are the confessions of faith of various Reformed churches. These documents express consensus on doctrine for the church adopting the confession. A few confessions are shared as subordinate standards (i.e. authorities subordinate to the Bible) by many denominations, which have made their choices from among the various creeds for primarily historical reasons.

Continental Reformed
Presbyterian
Congregationalist
Baptist

There's no such thing as " The Protestant Religion "   Protestants are a part of Christianity.......so is Catholosism. They are both the Christian religion.  By reformation, you are refering to the time when a Catholic monk named Martin Luther broke away from the Catholic church..... and started the Protestant movement. I never heard of " reformation confessons "  Verbal confessions is something only Catholics do to a priest  . Protestants only confess to the Lord  Jesus when they've done something wrong.They don't use a middle man.

   The Protestant reformation did not retain the Roman Catholic doctine or practice of auricular (private, spoken, into the ear) confession to a priest for absolution of sins. However St. Augustine was a key figure in the thinking of the Reformers, like Luther. One of Augustine's most significant writings is titled Confessions. See the website for additional explanation.
