A poor couple wanted to enrich each other for Christmas. She wanted to bring him joy by buying him a new bracelet for his ancient watch, since she did not have money she did it at the expense of cutting her long hair. He in turn sold that precious watch from his grandfather and bought her some combs for her beautiful hair. On Christmas Day their mutual gifts were useless. But their love saved their relationship throughout their whole life.

So glad they teach the term of TRANSUBSTANTIATION (unfortunatelly misspoken in the video)!
The Catholic Church believes in transubstantiation: the substance of bread and wine change while the accidents usually remain (weight, shape, taste, color, smell etc.), unlike the heretical view of consubstantiation (a parallel presence of both of bread and Body, wine and Blood) or pure transfinalization (a change of meaning of the Eucharistic elements).
The Council of Trent stated that the term "transubstantiation" is the best to express what happens with bread and wine in the Mass, so I suggest to use it preferably in English in place of just "consecration" (because also f. e. the altar is consacreted but "not transubstantiated").

At the conversion of St. Paul: Christ ~ the Church:

'Saul, Saul, why are you persecuting me? It is hard for you to kick against the goads.'
Then I asked, ‘Who are you, Lord?’
‘I am Jesus, whom you are persecuting,’ the Lord replied.

Ephesus - goddess Artemis and cult of the Roman Lord - the Cesar => laxity in faith and morals in midst of this multicultural pagan city

Smyrna - strong Jewish population (by an exception spared from Roman pressure) => Christians hid behind Jews to avoid persecution

Pergamum - large Amphitheater => sexual immorality

Thyatira - trade guilds (f. e. textile such as Lydia) => work but also prostitution (God will judge works)

Sardis - wealth and commerce => active in worldly matters (but dead in a spiritual sense)

Philadelphia - small => humble (just perseverance is needed)

Laodicea - famous calcium water springs and gymnasium with a thermal pool => lukewarmness (spiritual lethargy)
