After all the Catholic Church teaches that the Pope is infallible (not that different to the GB’s only channel claim), transubstantiation takes place during mass, unbaptised children can’t enter heaven etc etc, and while we can call it all bullshit, can we call them lies?
These are Watchtower lies.
I don't believe in Catholicism, Christianity or anything supernatural for that matter, but all of the above I remember being told and reading (at least in substance) in Watchtower publications, from the platform and various teachers while at the Kingdom Hall, conventions, presentations, etc.
The actual Catholic teachings?
A pontifical leader is not infallible, but can, on rare occasions declare an issue that has been decided after much years of study within the Roman Catholic Church (usually after there has been a serious question or issue) and, speaking for all members of the Church, declare, dogmatically, that the issue has been settled. Only that declaration is an infallable statement. Since the Church's foundation, this has only happened once, in 1950, when Pope Pius XII defined the doctrine of the Assumption of Mary in his papal bull, Munificentissimus Deus. It merely means that the Bishopric of Rome speaks as an official mouthpiece once an official decision has been arrived at by the rest of the people or members of the Church. The Episopate does not necessarily, of its own office, have this ability, as without a Church there would be no issues nor people to decide the matters.
Transubstantiation does takes place outside of Mass as well. There are holy relics which, reportedly hold pieces of the Eucharist which still undergo study by independent researchers (I don't have their names at present) and in the presence of often holy people literally change their chemical nature unlike actual Eucharistic elements. Why or how these things do this may be a trick or a natural occurrence, but it is a good trick or interesting phenomenon either way to watch.
And, the Church recognizes the validity of the sacrament in Orthodox Churches as well as Anglican Churches (which, by the way, have had similar "miracles," so to speak).
It is also not a teaching of the Roman Catholic Church that unbaptized children or even that non-Catholics do not enter heaven or gain salvation. What about Jews? It is official doctrine that they go to heaven. They also believe that people like Jehovah's Witnesses are saved without stepping one foot in a Catholic Church or ever believing a stitch of Catholic doctrine.
The USCCB and other local episcopates as well as the Holy See keeps the official CCC (Catholic Catechism) online, and any and all of its official teachings are on there for everyone to read at any time.
One thing the Watchtower was very good at lying about was teaching people about other religions (and what they believed) and claiming that once it did this, that 'we were now equipped to know the truth' about them.
That was a very big lie. If you have not updated your views about religion, atheism, agnosticism, philosophy and humanism since you left the Watchtower, you still believe in those lies of the big, bad W.
