What passages in the Catechism of the Catholic Church supports the doctrine of universal salvation?

Too many prerequisites envisioned by man! God wants only for you to believe (thus resist temptation) and help the poor and the needy to enter the Kingdom of God. As jesus said on the cross, salvation was already done/finished and we are only here now on Earth because we were born again to refine our soul through Him who is the only way to the Kingdom..
