首先定义：
Confirmation:坚礼，坚证，坚振，坚信，会员礼。。。意思都是一样的；

就是成人受洗或转换宗派后，或受洗小孩成年后, 正式宣布自己放弃以前的生活(宗派),加入新的宗派。同时，会众正式承认此人是新宗派的一员。

PCA有没有这种规定?当然有.

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.

你没听说过的原因是：大多数宗派把Confirmation包含在成人洗礼中了
