Looking for pope's encyclical addressing Protestantism

[ReturningToRome]

Hi,
I’m looking perhaps for a pope’s encyclical to guide me in a winsome, loving attitude toward Christians who are not Catholic. I have been a Lutheran for many years and am converting (reverting) to Catholicism because I believe it is the fullness of the faith, Christ’s True Church. I have been so focused on what is missing in Protestantism (specifically Lutheranism) as I learn more about the Catholic Church, preparing myself to be able to discuss the differences. But my wife is determined to remain Lutheran, and I have children who are Lutheran (my son-in-law is a Pastor), and grandchildren who will grow up Lutheran, and I am currently a Lutheran church worker, which I will give up at the end of this school year. There are lots of discussions ahead of me. I need to be guided in a loving and respectful attitude. The truth is the truth, but how can I speak it graciously, while acknowledging their sincere faith and love for the Lord that I have shared for many years.
Thanks, John

May I just add that if you haven’t come across it already, you will probably at some point need to be able to address the issue of “no salvation outside the Church”?

Here is a helpful explanation: catholic.com/thisrock/2005/0512fea3.asp

And “DOMINUS IESUS” ON THE UNICITY AND SALVIFIC UNIVERSALITY OF JESUS CHRIST AND THE CHURCH
