What has happened as a result of my being seen in churches of other Denominations?
A greater understanding of the Faith that we share with our separated brothers and sisters.
The last prayer that Our Lord prayed was “that they one.”
The Vatican II Document on Ecumenism begins by noting that the divisions within Christianity present a “scandal to the world.”
As has already been noted by others, as well as myself, praying in a hospital chapel, or any non-Catholic church, to include participating with our separated brothers and sisters in their worship services is apart from the ordinary weekly Mass and other services in which we participate. Just as non-Catholics are excluded from Communion, we are to refrain from participating in non-Catholic Communion services that lack the same meaning.
The lines of communication are opened, and those who have seen me have been more open to learning about the Catholic Faith. I am asked questions about what the Church actually teaches and can correct much misinformation that is out there.
This happens as well when people see me praying while traveling, as I open my Christian Prayer to pray the Morning or Evening Prayer, or am seen reading the Bible on my daily commute. Pray anywhere and any time.
