A servant is no greater than his master. Like Rome, the RC can operate from a double standard. Meanwhile, the The church actually began in dissent from those who sat in the seat of Moses over Israel, who were the historical instruments and stewards of Scripture, and inheritors of promises of Divine guidance, presence and perpetuation.
And instead the church established its Truth claims upon scriptural substantiation in word and in power, (Mt. 22:23-45; Lk. 24:27,44; Jn. 5:36,39; Acts 2:14-35; 4:33; 5:12; 15:6-21;17:2,11; 18:28; 28:23; Rm. 15:19; 2Cor. 12:12, etc.) while the alternative is sola ecclesia - the church alone being the supreme authority, with its presuppositions - but the RCs do not (wisely) or should not want to go there. Yet which is an admission that it is not Scriptural (which matters not under Rome).
Why is it so difficult for some to accept that there will be disagreements and differences in non-essential areas and that this strengthens our bonds of faith rather than diminishes them? Our Creator has given us an infinite variety in nature for an example.
