Here are some "simple" Catholic teachings that are very clear:
God's Nature is incomprehensible to men
God is absolutely perfect.
God is actually infinite in every perfection.
God is absolute veracity.
God is absolutely faithful.
God is absolute moral goodness or holiness.
God is absolute benignity.
God is absolutely immutable.
God is eternal.
God is immense or absolutely immeasurable.
God is everywhere present in created space.
God's knowledge is infinite.
God's knowledge is purely and simply actual.
God's Divine Will is infinite.
God is almighty.
God is the Lord of the heavens and of the earth.
God is infinitely just.
God is infinitely merciful.
God has created a good world.
The world had a beginning in time.
God alone created the world.
God keeps all created things in existence.
God, through His Providence, protects and guides all that He has created.
The first man was created by God.
Man consists of two essential parts - a material body and a spiritual soul.
Every human being possesses an individual soul.
God has conferred on man a supernatural destiny.
Our first parents, before the fall, were endowed with sanctifying grace.
Jesus Christ is true God and true Son of God.
Christ assumed a real body, not an apparent body.
Christ assumed not only a body but also a rational soul.
Christ was truly generated and born of a daughter of Adam, the Virgin Mary.
Only the second Divine Person became Man.
Not only as God but also as man Jesus Christ is the natural Son of God.
Christ was free from all sin, from original sin as well as from all personal sin.
Christ's human nature was passable.
The Son of God became man in order to redeem men.
Fallen man cannot redeem himself.
The God-man Jesus Christ is a high priest.
Christ offered Himself on the Cross as a true and proper sacrifice.
Christ by His sacrifice on the Cross has ransomed us and reconciled us with God.
Christ, through His passion and death, merited award from God.
After His death, Christ's Soul, which was separated from His Body, descended into the underworld.
On the third day after His death, Christ rose gloriously from the dead.
Christ ascended body and soul into Heaven and sits at the right hand of the Father.
There. That's a few of the "simple" infallible dogmas of the Catholic Church. Feel free to start at the top and work your way through showing how they are denied, modified or reinterpreted. I'm particularly curious about "God is eternal". "Fallen man cannot redeem himself" is a fun one too...

Most of those at first rapid scan appear to be quite straightforward.
IF
that was the sum total of the Catechism, a LOT of such problems would be over.
Catechism? Is this an "official" documented, referenced list?
