Do all Christian traditions expect a second coming of Christ?

No, I don't believe in a second coming and there are churches that don't. I not believe in the literal interpretation of the Bible and that the natural needs to be considered to understand the spiritual. The Bible should be interpreted spiritually or allegorical. The Bible is understood in a Natural and Spiritual way and Spiritual interpretation is preferred. The stories in the Bible are not historical events, but are lessons that have to be interpreted in the same way as the parables in the Gospels.

I belong to the Old Apostolic Church but some of there views I disagree with

Many Christians in multiple denominations lump the second coming of Christ in with the rapture as being the same, and thus there is a lot of confusion, when scripture is very clear.

The answer to your question is categorically no.

It really depends on whether you mean the rapture or the actual return of Christ to earth, and while some say they believe it, they believe it's symbolic - not a literal return. In scripture the rapture and the second coming are totally separate and distinctly events at two different times with two very different goals and purposes, for two totally different groups of people.

First is the rapture:

• This is Christ coming FOR his Bride - the Church,
• This is a joyous event- a celebration.
• Christians are raptured up into the clouds. [Word is from latin Rapturo and means to be caught up quickly by force.]
• Day of Christ - Term used only by Paul in the NT,
• Resurrection of the dead in Christ first, and then all those living Christians are caught up w Christ, just as the Bride in a Hebrew wedding is literally caught up and carried away for 7 days in the wedding chamber.
• This happens at The Last Trumpet - a widely-known Hebrew idiom for the 100th blast at Feast of Trumpets or Yom Teruah.

Totally separate time, place, goal and group of people is Second Coming:

• This is when Christ comes WITH his Bride
• At the Second Coming, Christ comes to earth and specifically touches his feet on the Mt of Olives, - same place and manner in which he ascended, and said he would come again in "Like Manner".
• This is the "Day of the Lord", and is used by Paul, Joel and Amos, Isaiah and in Acts, and always linked with terror, calamity and judgement. Sun turns black and the moon turns to blood.
• Joel 2:31, Acts 2:20 Isaiah 2:12,, Amos 5:18-20.
• Judgment and wrath is poured out on those who rejected and disobeyed God.
• Described as Terrible and day of woe/ destruction.

"The Day of the Lord" is a biblical term and theme used in both the Hebrew Bible (יֹום יְהוָה) and the New Testament (ἡμέρα κυρίου), as in "The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come" (Joel 2:31, cited in Acts 2:20).

In the Hebrew Bible, the meaning of the phrases refers to temporal events such as the invasion of a foreign army, the capture of a city and the suffering that befalls the inhabitants. This appears much in the second chapter of Isaiah.

In the New Testament, the "day of the Lord" may also refer to the writer's own times, or it may refer to predicted events in a later age of earth's history including the final judgment and the World to Come. It is used first by Isaiah and subsequently incorporated into prophetic and apocalyptic texts of the Bible. It relies on military images to describe the Lord as a "divine warrior" who will conquer his enemies.

Other prophets use the imagery as a warning to Israel or its leaders and for them, the day of the Lord will mean destruction for the biblical nations of Israel and/or Judah. This concept develops throughout Jewish and Christian Scripture into a day of divine, apocalyptic judgment at the end of the world."

I know as a fact that many reformed/ Calvinists disregard or symbolize the End Times events. One specific example is an Evangelical Free Church of America - of which each congregation is autonomous, and self-led [no higher synod, or council] The pastor himself is Ammillennial.

In another EFCA, in which the leaders are also predominately Calvinist, they do not believe in the literal rapture, but they believe that Christ will return to earth - so the second coming. In another example, a branch of 7th day Adventists believe in the second coming, and some events of the tribulation, such as the Anti-Christ, but no literal physical rapture.

While it is true that most denominations believe that Christ will return, there are many that do not believe in the literal rapture, and also reject many events of Revelation as purely symbolic/apocalyptic.

On the whole, yes, virtually all traditions expect his return. The only exceptions I know of are theological liberals, who don't regard the Bible or its foretellings (even on the lips of Jesus) to be reliable, and some few preterists (viz., sometimes called full preterists or hyper-preterists, in distinction from partial preterists, who do expect a final return). Full preterists claim that even the resurrection of the dead (spiritualized) has already happened. This seems an odd view, but Paul met it and condemned it in his day too (2 Tim 2:16-18).
