A few of his recent tweets:
"Faith is not something decorative or for show.
To have faith means to put Christ
truly at the centre of our lives."
"The love of God is not something vague
or generic; the love of God has a name and a face:
"Don't be afraid to ask God for forgiveness.
He never tires of forgiving us.
God is pure mercy."
"We cannot be Christians part-time.
If Christ is at the center of our lives,
he is present in all that we do."
"One cannot separate Christ and the Church.
The grace of Baptism gives us the joy
of following Christ in and with the Church."
Such pearls of wisdom so clearly stated. Check out the Holy Father's twitter account.
