During Pope Benedict’s Apostolic visit to the USA, remembering that ‘apostle’ means’ ‘sent one’.

From yesterday’s gospel:

Whoever rejects me and does not accept my words
has something to judge him: the word that I spoke,
it will condemn him on the last day,
because I did not speak on my own,
but the Father who sent me commanded me what to say and speak.

Jesus speaking to the apostles in the gospel from today’s papal Mass:
As the Father has sent me, even so, I am sending you.

From today’s gospel:

Amen, amen, I say to you, whoever receives the one I send
receives me, and whoever receives me receives the one who sent me.”

From Ignatius of Antioch: c.108
Be eager to be firmly established in the doctrines of the Lord and of the Apostles…be submissive to the Bishop as Jesus Christ was to the Father, and the Apostles to Christ…that there may be unity…All who belong to God and Jesus Christ are with the bishop; and all who repent of schism and come into the unity of the Church will also belong to God that they may be living according to Jesus Christ.
Irenaeus of Lyon: c. 190
Therefore we will refute those who hold unauthorized assemblies–by pointing to the tradition of the greatest and oldest church, a church known to all men which was founded and established at Rome by the most renowned apostles Peter and Paul. The tradition the church has from the Apostles has bee proclaimed to all men and has come down to our own day through the succession of bishops. for this church has the position of leadership and authority.
