It’s just a coincidence that you’re theism happens to be as nominally orthodox as it turns out to be. The Trinity doesn’t conflict with universalism, so you just so happen to affirm the Trinity.Your universalism is heretical, and where your remaining theology is orthodox, it’s orthodox by chance. Like being accidentally innocent of murder because the gun misfired.
Ouch! On non-universalist theological issues I am only orthodox "by chance" and thus only "nominally orthodox" (on universalist issues I am simply a heretic). I think that Steve's point is that he believes that my deepest convictions about God are idolatrous and where my surface beliefs appear to be orthodox this is simply a matter of convenience (because they do not contradict my deeper, universalist convictions). As a result they are not expressions of genuine faith but mere nominal faith.
I must confess to being somewhat surprised that Steve, who does not know me at all, feels so confident in his analysis of my inner life as to be able to make such claims. I hope that if he knew me personally then he would come to see that he is quite mistaken. One day he will know me personally and we'll have heartfelt fellowship. For now I can only made claims which he may simply not believe. However, for the record, here goes ...
The revelation of God as triune - Father, Son and Spirit - is far more fundamental to my faith than universalism was, is, or ever will be. It is the heart of my Christianity and I would surrender universalist theology any day before surrendering trinitarian theology. It is not something I believe by accident or as a mater of convenience, and it is not nominal.
I hope that helps.
However, I am make no apology for being thrilled that the beautiful, glorious God and Father of our Lord Jesus is the one who is reconciling the whole world to himself through Christ and in the Spirit. Universalism is compatible with orthodox trinitarian faith - deal with it!
