Eschatology is on a list of things that are considered described as
in dubiis libertas
so you have freedom to disagree as long as you are within bounds of what the Catechism says. I would say that there may be multiple spiritual comings of Christ depending on what you mean by “coming” but what most people talk about when they talk about “second coming” is not a “coming in judgment” but an actual physical returning. Hence, it’s a second coming. The second coming.
True and it is good that the church gives us such wide freedom on these subjects; I believe I’m well within bounds of what the catechism both restricts and allows.
The spiritual and expansive presence of Christ is in fact gotten from His own dogmatic statement; “Behold I am with you always even until the end of the world.” But this takes faith and communion with Him on our part; to see or behold; Him. Do we really see Him, in the Sacraments, substantially in the Eucharist, in person in the Sacrament of Reconciliation and so forth. “Where I am there my servant shall be” do we behold Him in those who are lacking in anything; “Whatsoever you did to them you did to me.” So I think you would see where this is going; it’s not numerous spiritual comings, which I would also point out would necessitate goings, it’s the ever present Lord. But in the second coming the glorified physical Christ, returns, coming on the clouds with great power as I’m sure you’re very familiar with the Scripture references that speak about this will come to mind.
Unless you think that such things as a beast with ten horns and seven heads coming out of the water are supposed to be literal. If you are talking about the Olivet Discourse, much of it is actually unraveling in the Bible
