首先定義：
Confirmation:堅禮，堅證，堅振，堅信，會員禮。。。意思都是一樣的；

就是成人受洗或轉換宗派後，或受洗小孩成年後, 正式宣布自己放棄以前的生活(宗派),加入新的宗派。同時，會眾正式承認此人是新宗派的一員。

PCA有沒有這種規定?當然有.

PCA Book of Church Order:

57-4. It is recommended, as edifying and proper, that baptized persons, when admitted by the Session to the Lord’s Supper, make a public profession of their faith in the presence of the congregation. But in all cases, there should be a clear recognition of their previous relation to the church as baptized members.

你沒聽說過的原因是：大多數宗派把Confirmation包含在成人洗禮中了
