Crowds wait for Pope Francis to deliver a Mass at a huge park in Quito, Ecuador's capital

At a Mass on Monday, he hinted that changes that some Catholics might consider "scandalous" could be coming to the church

That night, outside the Vatican Embassy, supporters sang and prayed until the Pope shooed them away

CNN  — 

Tuesday is Pope Francis’ second full day in Ecuador, the first stop on his whirlwind tour of three South American countries.

He is celebrating a Mass at around 11:30 a.m. at a huge park in Quito, Ecuador’s capital. Crowds have been in place for hours – as has the choir, which has been singing a song about “Santo Padre” (Holy Father) almost all morning. (I will be hearing that song in my sleep tonight, for sure.)

At a Mass on Monday, the Pope focused his sermon on the family and hinted that changes that some Catholics might consider “scandalous” could be coming to the church. Francis was a bit vague about what the scandal might be, but he asked Catholics to pray that bishops meeting this fall could find “concrete solutions” to some of the challenges facing modern families. Most likely, that refers to how the church ministers to divorced Catholics and LGBT families.

After the Mass, the Pope met an old friend and had lunch with the Jesuit community. (Francis is the first Jesuit pope.) He also took many, many selfies throughout the day and shook many, many hands. It took him nearly an hour to get through the line Monday night at the presidential palace. Honestly, I don’t know where the Pope gets the energy. He’s 78, but he has the smile and the stamina of a much younger man.

Finally, the Pope said goodnight and went to bed. Except the crowd wouldn’t let him, singing and praying outside the Vatican Embassy, where he’s staying in Quito. Finally, the Pope came out, gave the crowd a quick blessing and then firmly told them to go home and let the neighbors get some rest.
