Incidentally, before anyone jumps on him-or-her, I’ve checked and so far as I can tell this isn’t BAaron.
Most of the universalists here, myself included, are trinitarians (with a few members who are unitarian and one or two modalists).
So unless you don’t worship the Jesus Who is the Incarnated Second Person of the single substantial Lord God Most High, equal in Glory and co-eternal in Majesty with the Persons of the Father and the Holy Spirit, uncreated, ungraspable, omnipotent, omnipresent, omniscient, Almighty, only begotten of the Father, from Whom proceeds the Holy Spirit, God and Man, of the substance of the Father begotten before the worlds, and of the substance of His mother, born in the world, altogether God and altogether Man, of a reasonable soul and human flesh subsisting, equal to the Father as regarding His Godhood, inferior to the Father as regarding His humanity, not two Christs but one Christ, not by the conversion of the Godhead into flesh but by taking of the Manhood into God, altogether one by unity of Person not by confusion of substances, Who suffered under Pontius Pilate for our salvation, descended into Hell, and rose again from the dead on the third day, ascended into Heaven, sitting on the right hand of the Father God Almighty, from where He shall come to judge the living and the dead, resurrecting the good and the evil, the good into life from God and the evil into judgment from God… {inhale}
…then in fact most of us worship the same Jesus you do. 
(We’ve been discussing the so-called Athanasian Creed recently, so I took the opportunity to make a bit of a point for the sake of some other readers.)
The main thing trinitarian Christian universalists and trinitarian Christian non-universalists disagree on is what it means for impenitent sinners to go into ‘eonian judgment’ and/or the ‘eonian fire’. Otherwise, Christian universalists have the same disagreements among ourselves as Christian non-universalists do, for the most part.
I will however say that I have never once met a trinitarian Christian universalist (or a non-trinitarian one, for that matter!) who thought that Christ’s salvation amounted only to propping open a door, or even only propping open a door while calling someone inside (which you should note does involve more activity from Christ than propping open a door!) I don’t suppose it’s impossible for universalists to believe that, especially if they come from the Arminian side of the aisle, where frankly I find that kind of thinking more prevalent than anywhere else. (I’ve even seen it vehemently proposed by Arminians against my belief, common to every universalist I know, that Christ goes out persistently after the 100th sheep until He finds and returns with it! But many Arms would believe that, too.)
On the contrary, Christian universalists typically agree with Calvinists (as well as some Arminians) that God doesn’t only open the way for us but persists in leading us home, empowering us and pushing us to go (even dragging all men to Himself, as Jesus emphatically puts it in John’s Gospel.) Those of us (myself included) who affirm God’s punishment in this life and after death (including what counts as hell), would say that’s part of the pushing as well as leading; others of us would say the pushing goes quite a bit farther than that!
At any rate, I don’t know anyone here, including those of us who have come from a more-or-less Arminian background, who believe that Jesus Christ is any kind of static tool for our salvation (or is in any way static). We worship our Lord and Savior as the Living God Who is mighty to save! We disagree with Calvinists, broadly speaking, about the scope of God’s action to save; we disagree with Arminians, broadly speaking, about the persistence of God’s action to save. Everything else is a detail of those disagreements–and of those agreements! (Since we agree with each of them the other way around.)
It’s much like how as trinitarians we agree with modalists that Christ is God Most High, and agree with Arians that the Son and the Father are distinct Persons with the Son being under the authority of the Father (and yet agree with both of them that there is only one God Most High).
Don’t you believe Christ (as God) can save everyone? (There, you can be absolutely sure I didn’t leave Christ’s involvement out. )
I not only agree, but I think most of the universalists here agree with that, too. I can recall one or two here who think Christ has already totally completed their salvation; but such people have a tendency to think of themselves as sinless superbeings who can preach at other people without listening to what the other people say (while attributing false motives to the other people). Such people are tolerated here only a short time, whether they are universalists or not (I’ve known some non-universalists like that, too), before being sent off on probation.
So hopefully such people won’t be a problem for you here.
Well, actually you’re asking about metaphysical and thus philosophical topics; which involve answers in principle logic, including with reference to scriptural testimony.
But we discuss scriptures a lot here, too. Maybe you should spend a few months reading around here first, so you can find out what various members here actually believe?
