Your church uses natural timing to space of children which still means LIMITING THEM no matter what you want to call it.

There were efforts in the very early days following Christ to once again fall under them and place them upon the Gentile and new Jewish believers alike as Peter was being persuaded to do by the Jewish leaders but it was addressed.
Today we observe The Lords Commandments and His teachings and the much fewer laws set by ones like Paul, Peter, John, etc for believers in the "churches" for our conduct in and out of church including rules inside a marriage relationship. For many that suffices and is enough to abide in. For other churches they need volumes upon volumes of more of mans rules "Much like the laws" with some church figureheads holding them over their heads all their lives.
