Ahh Yes, but did not our Lord tell the Apostles to go forth and teach the gospels, and
"Whosoever shall not receive you, NOR HEAR YOUR WORDS, going forth out of that house or city, shake off the dust from your feet. Amen I say to you, it shall be more tolerable for Sodom and Gommorah in the day of judgement than for that city". Ecumenism is contrary to everything in scripture and Catholic teaching and hence the church is in serious default.
10:5 These twelve Jesus sent: commanding them, saying: Go ye not into the way of the Gentiles, and into the city of the Samaritans enter ye not.
10:5 hos duodecim misit Iesus praecipiens eis et dicens in viam gentium ne abieritis et in civitates Samaritanorum ne intraveritis
10:6 But go ye rather to the lost sheep of the house of Israel.
10:6 sed potius ite ad oves quae perierunt domus Israhel
10:7 And going, preach, saying: The kingdom of heaven is at hand.
10:7 euntes autem praedicate dicentes quia adpropinquavit regnum caelorum
10:8 Heal the sick, raise the dead, cleanse the lepers, cast out devils: freely have you received, freely give.
10:8 infirmos curate mortuos suscitate leprosos mundate daemones eicite gratis accepistis gratis date
10:9 Do not possess gold, nor silver, nor money in your purses:
10:9 nolite possidere aurum neque argentum neque pecuniam in zonis vestris
10:10 Nor scrip for your journey, nor two coats, nor shoes, nor a staff; for the workman is worthy of his meat.
10:10 non peram in via neque duas tunicas neque calciamenta neque virgam dignus enim est operarius cibo suo
10:11 And into whatsoever city or town you shall enter, inquire who in it is worthy, and there abide till you go thence.
10:11 in quamcumque civitatem aut castellum intraveritis interrogate quis in ea dignus sit et ibi manete donec exeatis
10:12 And when you come into the house, salute it, saying: Peace be to this house.
10:12 intrantes autem in domum salutate eam
10:13 And if that house be worthy, your peace shall come upon it; but if it be not worthy, your peace shall return to you.
10:13 et siquidem fuerit domus digna veniat pax vestra super eam si autem non fuerit digna pax vestra ad vos revertatur
10:14 And whosoever shall not receive you, nor hear your words: going forth out of that house or city shake off the dust from your feet.
10:14 et quicumque non receperit vos neque audierit sermones vestros exeuntes foras de domo vel de civitate excutite pulverem de pedibus vestris
10:15 Amen I say to you, it shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city.
10:15 amen dico vobis tolerabilius erit terrae Sodomorum et Gomorraeorum in die iudicii quam illi civitati
10:16 Behold I send you as sheep in the midst of wolves. Be ye therefore wise as serpents and simple as doves.
10:16 ecce ego mitto vos sicut oves in medio luporum estote ergo prudentes sicut serpentes et simplices sicut columbae
10:17 But beware of men. For they will deliver you up in councils, and they will scourge you in their synagogues.
10:17 cavete autem ab hominibus tradent enim vos in conciliis et in synagogis suis flagellabunt vos
10:18 And you shall be brought before governors, and before kings for my sake, for a testimony to them and to the Gentiles:
10:18 et ad praesides et ad reges ducemini propter me in testimonium illis et gentibus
10:19 But when they shall deliver you up, take no thought how or what to speak: for it shall be given you in that hour what to speak.
10:19 cum autem tradent vos nolite cogitare quomodo aut quid loquamini dabitur enim vobis in illa hora quid loquamini
10:20 For it is not you that speak, but the Spirit of your Father that speaketh in you.
10:20 non enim vos estis qui loquimini sed Spiritus Patris vestri qui loquitur in vobis
10:21 The brother also shall deliver up the brother to death, and the father the son: and the children shall rise up against their parents, and shall put them to death.
10:21 tradet autem frater fratrem in mortem et pater filium et insurgent filii in parentes et morte eos adficient
10:22 And you shall be hated by all men for my name's sake: but he that shall persevere unto the end, he shall be saved.
10:22 et eritis odio omnibus propter nomen meum qui autem perseveraverit in finem hic salvus erit
10:23 And when they shall persecute you in this city, flee into another. Amen I say to you, you shall not finish all the cities of Israel, till the Son of man come.
10:23 cum autem persequentur vos in civitate ista fugite in aliam amen enim dico vobis non consummabitis civitates Israhel donec veniat Filius hominis
10:24 The disciple is not above the master, nor the servant above his lord.
10:24 non est discipulus super magistrum nec servus super dominum suum
10:25 It is enough for the disciple that he be as his master, and the servant as his lord. If they have called the goodman of the house Beelzebub, how much more them of his household?
10:25 sufficit discipulo ut sit sicut magister eius et servus sicut dominus eius si patrem familias Beelzebub vocaverunt quanto magis domesticos eius
10:26 Therefore fear them not. For nothing is covered that shall not be revealed: nor hid, that shall not be known.
10:26 ne ergo timueritis eos nihil enim opertum quod non revelabitur et occultum quod non scietur
10:27 That which I tell you in the dark, speak ye in the light: and that which you hear in the ear, preach ye upon the housetops.
10:27 quod dico vobis in tenebris dicite in lumine et quod in aure auditis praedicate super tecta
10:28 And fear ye not them that kill the body, and are not able to kill the soul: but rather fear him that can destroy both soul and body in hell.
Indeed he did ... however, this is a warning to the Gentile Christians not to see their faith as superiority over the Jews.
This is the beautiful promise that when the Jews return to the fullness of their faith (i.e. the Church), they will be grafted back onto what has always been their own native root and the result will be doubly graced.
The statement that the unbelief of the Jews was an integral part of God's plan (not man's) to enable the Gentiles to be saved but that when the "full number" of the Gentiles has come in (presumably at the end of the age of salvation history), the "hardening" resulting in the Jews' unbelief will be removed and "all Israel will be saved".
