What is Catholicism?

No? (what is the correct answer if the Pope was never the "man of Lawlessness" from end time prophecy?)
The "Antichrist" as understood in end time prophecy should be a lot more impressive than the Pope.

Personally, none.
A "good Catholic" is only expected to believe the Doctrines of the Church and the 'ex cathedra' statements of the Pope.

Has the current Pope (Francis) even made any 'ex cathedra' statements?

 

I found the answer. The last 'ex cathedra' statement was by Pope Pius XII (1854):

.. by the authority of our Lord Jesus Christ, of the Blessed Apostles Peter and Paul, and by our own authority, we pronounce, declare, and define it to be a divinely revealed dogma:

that the Immaculate Mother of God, the ever Virgin Mary, having completed the course of her earthly life, was assumed body and soul into heavenly glory.

Hence if anyone, which God forbid, should dare willfully to deny or to call into doubt that which we have defined, let him know that he has fallen away completely from the divine and Catholic Faith.
​

So that was the last thing that a Pope said that all Catholics MUST believe (because the Pope said it).

 

Small "a" for "antichrist" ... meaning anyone or anything that opposes Christ.

Give me an example of "Papal doctrine" to beware of in a Baptist church.

• There is no effort to change from Credobaptism (believer's baptism) to Paedobaptism (infant baptism).
• No one is arguing for the "real presence" on the Eucharist rather than a symbolic "do this in memory of me".
• No one is advocating for Bishops over multiple congregations to limit the local autonomy.
• No one is claiming water baptism is not an outward sign of an inner change that has already taken place.

• There are people that advocate an equal role for women, but the Pope rejects such a policy, so that is not a "Papal doctrine".
• There are those who seek to use God as a slot machine to get wealthy, but I have never heard the Pope preach a "Prosperity Gospel".

So what "Papal doctrine" are you thinking of?

 

Yup.

1 Corinthians 15:50-52 [NKJV]

50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; nor does corruption inherit incorruption. 51 Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed-- 52 in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed.​

 

I have absolutely no problem with people that want to baptize in the name of Jesus Christ (only), or with people that want to baptize in the name of the Father, Son and Holy Spirit.
I disagree with ‘Free Will’ (being a Particular Baptist), but do not view those that hold to cooperation in their salvation as ‘antichrists’.
Dispensationalism was popularized by Scofield (who was not a Jesuit) and has some valid scriptural observations about the past dispensations of God’s Grace even as it makes questionable assumptions about eschatology.
Those that use, and those that abstain from “organs, pews, altars and stained glass” both do so according to 1 Corinthians 10:31 and “to the glory of God”, so I am in full support of the body of Christ doing anything to the glory of God.

I even accept YOUR views as your attempt to somehow bring glory to God by abhorring what you believe God abhors; I just cannot see the evil in an organ playing “Amazing Grace” to a room full of people praising Christ that believe that He could snatch them out of this world at any moment and begin pouring the wrath of God on the ungodly.
