Every PCA church should use discipline with its members with respect to infant baptism. The question is how that discipline should be carried out. Discipline takes many forms - from the informal to the formal. From counsel to excommunication.

My personal opinion would be to permit a non-paedobaptist to join (in light of the PCA's sole requirement of a credible profession of faith, and not confessional subscription by members) and to exhort, counsel and encourage (pastoral discipline) families to not neglect infant baptism.

More often than not, a family that stays committed to a PCA church for a length of time where tolerance is exhibited, but the truth of the Scripture is consistently and unashamedly proclaimed from the pulpit and in education classes, will come to adopt paedobaptism.

"The heart is the main thing in true religion...It is the hinge and turning-point in the condition of man's soul. If the heart is alive to God and quickened by the Spirit, the man is a living Christian. If the heart is dead and has not the Spirit, the man is dead before God." (J.C. Ryle)
